colspan="1.5" not working, any other ideas? - html

this is what table i need
I can easily get first and second row good but when i'm trying to make row third, I'm destroying row two.
I tried with width attribute and colspan but nothing work.
<table border="1px" width="100%">
<tr>
<td colspan="6">Cell 1</td>
</tr>
<tr >
<td colspan="3">Cell 2</td>
<td colspan="3" >Cell 3</td>
</tr>
<tr>
<td colspan="2">Cell 4</td>
<td colspan="2">Cell 5</td>
<td colspan="2">Cell 6</td>
</tr>
</table>


A <table> will conform to it's content by default so there's no need for each column to be equal in width. So manually assign equal column widths by assigning table-layout: fixed to <table> then an equal width for each column by either assigning each width to the <th> in the <thead> of the first <tr> or lacking that assign widths to the <td> of the first <tr> (of course td or th as a selector works as well), see example below.
table {
table-layout: fixed;
}
td {
width: 16.5%;
text-align: center;
}
<table border="1px" width="100%">
<tr>
<td colspan="6">I</td>
</tr>
<tr>
<td colspan="3">II</td>
<td colspan="3">III</td>
</tr>
<tr>
<td colspan="2">IV</td>
<td colspan="2">V</td>
<td colspan="2">VI</td>
</tr>
</table>

HTML table row with double height

I am trying to add a row with double height to that of other row. But unable to make. Not sure what is wrong.
<table border="1">
<tr>
<td rowSpan="2">A1</td>
<td rowSpan="2">A2</td>
<td rowSpan="2">A3</td>
<td rowSpan="2">A4</td>
</tr>
<tr>
</tr>
<tr>
<td>C1</td>
<td>C2</td>
<td>C3</td>
<td>C4</td>
</tr>
</table>

You'll need some css to set the height of the row;
table td, tr {
height: 30px;
}
table td, tr {
height: 30px;
}
<table border="1">
<tbody>
<tr>
<td rowSpan="2">A1</td>
<td rowSpan="2">A2</td>
<td rowSpan="2">A3</td>
<td rowSpan="2">A4</td>
</tr>
<tr>
</tr>
<tr>
<td>C1</td>
<td>C2</td>
<td>C3</td>
<td>C4</td>
</tr>
</tbody>
</table>
Note; You should add a tbody to your table; What is the purpose for HTML's tbody?

Are you trying to do that ?
<table border="1">
<tr>
<td>A1</td>
<td>A2</td>
<td>A3</td>
<td rowspan="2">A4/B4 <br>(2 rows)</td>
</tr>
<tr>
<td>B1</td>
<td>B2</td>
<td>B3</td>
</tr>
<tr>
<td>C1</td>
<td colspan="2">C2/C3 <br>(2 cols)</td>
<td>C4</td>
</tr>
</table>

The rowspan property should only be used if you are trying to have one cell appear across two rows (as if you are using the Merge Cells functionality on Excel). If you want to make one row twice as high as the other, this is a display property and should be done with css or inline styling. The middle (row) should also be removed.
If this is just a general example and you need to use it on something more complex. If you use rowspan on say 1 element, you will need to make sure that the following row has 1 less td element otherwise it will not display correctly.
<table border="1">
<tr style="height: 50px">
<td >A1</td>
<td >A2</td>
<td >A3</td>
<td >A4</td>
</tr>
<tr>
<td>C1</td>
<td>C2</td>
<td>C3</td>
<td>C4</td>
</tr>
</table>

Having height of last row take all the space with rowspan

I have a table structure like this
And the html structure is this
<table class="table table-bordered">
<thead>
<tr>
<th>Hierarchy</th>
<th>Operations</th>
</tr>
</thead>
<tbody>
<tr>
<td class="history-hierarchy" rowspan="4">
<div><!-- Tree structure is loaded here dynamically --></div>
</td>
</tr>
<tr>
<td class="history-text">
Equipment A700/005 is added.
</td>
</tr>
<tr>
<td class="history-text">
System instance SYSI/0002 is added.
</td>
</tr>
<tr>
<td class="history-text">
Equipment 7100/001 is replaced with 7100/002
</td>
</tr>
</tbody>
</table>
If you see the image, the Operations columns height is adjusting itself based on the Hierarchy columns height, I am looking for some way if possible to have the heights of operation column fixed say 10px and whatever space is left the last row's operation column should consume it.
So the operations column will not looke weird having so much height.
Is it possible?

the approach you are using is correct, you can use rowspan="2" on the last row as shown in my snippet.
table {height: 600px}
table td {border:1px solid red; vertical-align:top}
td.history-text {height: 20px}
<table class="table table-bordered">
<thead>
<tr>
<th>Hierarchy</th>
<th>Operations</th>
</tr>
</thead>
<tbody>
<tr>
<td class="history-hierarchy" rowspan="4">
<div>Tree structure is loaded here dynamically</div>
</td>
<td class="history-text">
Equipment A700/005 is added.
</td>
</tr>
<tr>
<td class="history-text">
System instance SYSI/0002 is added.
</td>
</tr>
<tr>
<td class="history-text" rowspan="2">
Equipment 7100/001 is replaced with 7100/002
</td>
</tr>
</tbody>
</table>

Creating columns inside a column

This is the picture of what the output should look like:
I want to create something like this (see the attached photo). But I can't do the same thing. I already tried using div and table tags.
This is what I've been doing
<table class="table table-bordered">
<thead>
<tr>
<th class="col-xs-1">ProjectID</th>
<th>Program/Project</th>
<th class="col-xs-1">Office/Unit</th>
<th class="col-xs-1">General Description</th>
<th class="col-xs-1">Methods</th>
<th> Schedule/Milestone
<table>
<tr>
<td class="col-xs-1">Jan</td>
<td class="col-xs-1">Feb</td>
<td class="col-xs-1">Mar</td>
<td class="col-xs-1">Apr</td>
<td class="col-xs-1">May</td>
<td class="col-xs-1">Jun</td>
<td class="col-xs-1">Jul</td>
<td class="col-xs-1">Aug</td>
<td class="col-xs-1">Sep</td>
<td class="col-xs-1">Oct</td>
<td class="col-xs-1">Nov</td>
<td class="col-xs-1">Dec</td>
</tr>
</table>
</th>
<th class="col-xs-1">Source of funds</th>
<th class="col-xs-1">Approved Budget Ceiling (ABC)</th>
</tr>
</thead>
<tbody>
<tr>
<td>Empty</td>
<td>Empty</td>
<td>Empty</td>
<td>Empty</td>
<td>Empty</td>
<td>
<!-- THIS IS WHERE I CAN'T GET IT RIGHT -->
<table>
<tr>
<td class="col-xs-1">1</td>
<td class="col-xs-1">2</td>
<td class="col-xs-1"> 3</td>
<td class="col-xs-1"> 4</td>
<td class="col-xs-1"> 5</td>
<td class="col-xs-1"> 6</td>
<td class="col-xs-1"> 7</td>
<td class="col-xs-1"> 8</td>
<td class="col-xs-1"> 9</td>
<td class="col-xs-1"> 10</td>
<td class="col-xs-1"> 11</td>
<td class="col-xs-1"> 12</td>
</tr>
</table>
</td>
<td>Empty</td>
<td>Empty</td>
</tr>
</tbody>
</table>
But the output of this code looks like this:
I am using bootstrap to create my website.

What you're trying to do isn't really possible, because you are breaking up the table structure in two. This means that each cell in the 2nd table (1,2,3..) is going to have the width of its' contents and won't be affected by the width of the header cells (Jan, Feb, Mar...).
This is why you're seeing this.
One way to fix this is by applying table-layout: fixed on both tables, and then giving each td a fixed width and the display: inline-block property.
.milestone-table {
table-layout: fixed;
width: 390px; /*optional*/
}
.milestone-table td {
width: 30px;
display: inline-block;
}

Targetting <th> element within the first occurence of Table within document

I'm trying to solve a specific problem with CSS selectors. I have the foillowing HTML:
<table class="Layout">
<tr>
<td>
<table class="Region">
<tbody>
<tr>
<th align="left">Header 1</th>
</tr>
<tr>
<td>
<table class="SelectionTable">
<tbody>
<tr>
<td>Text 1</td><td>Text 2</td>
</tr>
</tbody>
</table>
</td>
</tr>
</tbody>
</table>
</td>
<td valign="top"></td>
<td valign="top">
<table class="Region">
<tr>
<th align="left" colspan="2">Header 2</th>
</tr>
<tr>
<td>Text 1</td><td>Text 2</td>
</tr>
</table>
</td>
</tr>
</table>
What I need to do is select the first occurence of the class "Region" within the document, and then select the th element, which contains the text "Header 1" (there will only be 1 th element within these tables). My reason for this is so i can apply a background color to this element.
I currently have this css which applies background color to the th elements of the two "Region" tables:
TABLE.Region TH {background-color: #00A5DB;}
But I want to apply background-color: #BAD80A to only the first occurence of "Region"
I know I can achieve this using javascript and I know this is an old way of arranging elements on a page, but this is a change to a company intranet with many pages, so changing just the style sheet would be by far the quickest way of acheiving this, as I don't really have the time to make sweeping changes at the moment! We use IE11 as our main browser, so the answer can be quite specific if necessary.
Any help would be appreciated!
Thanks

You can use the first-child psuedo-selector on the td and then target the th inside .region.
Here's a demo:
td:first-child .Region th {
background-color: red;
}
<table class="Layout">
<tr>
<td>
<table class="Region">
<tbody>
<tr>
<th align="left">Header 1</th>
</tr>
<tr>
<td>
<table class="SelectionTable">
<tbody>
<tr>
<td>Text 1</td>
<td>Text 2</td>
</tr>
</tbody>
</table>
</td>
</tr>
</tbody>
</table>
</td>
<td valign="top"></td>
<td valign="top">
<table class="Region">
<tr>
<th align="left" colspan="2">Header 2</th>
</tr>
<tr>
<td>Text 1</td>
<td>Text 2</td>
</tr>
</table>
</td>
</tr>
</table>

/*Both work fine*/
table.Layout td:first-child th{
background: #555;
}
td:first-child th{
background: #555;
}

How do you use colspan and rowspan in HTML tables?

I don't know how to merge rows and columns inside HTML tables.
Can you please help me with making such a table in HTML?

If you're confused how table layouts work, they basically start at x=0, y=0 and work their way across. Let's explain with graphics, because they're so much fun!
When you start a table, you make a grid. Your first row and cell will be in the top left corner. Think of it like an array pointer, moving to the right with each incremented value of x, and moving down with each incremented value of y.
For your first row, you're only defining two cells. One spans 2 rows down and one spans 4 columns across. So when you reach the end of your first row, it looks something like this:
<table>
<tr>
<td rowspan="2"></td>
<td colspan="4"></td>
</tr>
</table>
Now that the row has ended, the "array pointer" jumps down to the next row. Since x position 0 is already taken up by a previous cell, x jumps to position 1 to start filling in cells. * See note about difference between rowspans.
This row has four cells in it which are all 1x1 blocks, filling in the same width of the row above it.
<table>
<tr>
<td rowspan="2"></td>
<td colspan="4"></td>
</tr>
<tr>
<td></td>
<td></td>
<td></td>
<td></td>
</tr>
</table>
The next row is all 1x1 cells. But, for example, what if you added an extra cell? Well, it would just pop off the edge to the right.
<table>
<tr>
<td rowspan="2"></td>
<td colspan="4"></td>
</tr>
<tr>
<td></td>
<td></td>
<td></td>
<td></td>
</tr>
<tr>
<td></td>
<td></td>
<td></td>
<td></td>
<td></td>
<td></td>
</tr>
</table>
* But what if we instead (rather than adding the extra cell) made all these cells have a rowspan of 2? The thing you need to consider here is that even though you're not going to be adding any more cells in the next row, the row still must exist (even though it's an empty row). If you did try to add new cells in the row immediately after, you'd notice that it would start adding them to the end of the bottom row.
<table>
<tr>
<td rowspan="2"></td>
<td colspan="4"></td>
</tr>
<tr>
<td></td>
<td></td>
<td></td>
<td></td>
</tr>
<tr>
<td rowspan="2"></td>
<td rowspan="2"></td>
<td rowspan="2"></td>
<td rowspan="2"></td>
<td rowspan="2"></td>
</tr>
<tr>
<td></td>
</tr>
</table>
Enjoy the wonderful world of creating tables!

I'd suggest:
table {
empty-cells: show;
border: 1px solid #000;
}
table td,
table th {
min-width: 2em;
min-height: 2em;
border: 1px solid #000;
}
<table>
<thead>
<tr>
<th rowspan="2"></th>
<th colspan="4"> </th>
</tr>
<tr>
<th>I</th>
<th>II</th>
<th>III</th>
<th>IIII</th>
</tr>
</thead>
<tbody>
<tr>
<td></td>
<td>1</td>
<td>2</td>
<td>3</td>
<td>4</td>
</tr>
</tbody>
</table>
References:
td element.
th element.
tbody element.
thead element.
table element.

If anyone is looking for a rowspan on both the left AND on the right,
here is how you can do it:
table {
border-collapse: collapse;
}
td {
padding: 20px;
border: 1px solid black;
text-align: center;
}
<table>
<tbody>
<tr>
<td rowspan="2">LEFT</td>
<td> 1 </td>
<td> 2 </td>
<td> 3 </td>
<td> 4 </td>
<td rowspan="2">RIGHT</td>
</tr>
<tr>
<td> 5 </td>
<td> 6 </td>
<td> 7 </td>
<td> 8 </td>
</tr>
<tr>
<td> - </td>
<td> - </td>
<td> - </td>
<td> - </td>
<td> - </td>
<td> - </td>
</tr>
</tbody>
</table>
Alternatively, if you want to add the LEFT and RIGHT to an existing rowset, you can achieve the same result by throwing them in with a collapsed colspan in between:
table {
border-collapse: collapse;
}
td {
padding: 20px;
border: 1px solid black;
text-align: center;
}
<table>
<tbody>
<tr>
<td rowspan="3">LEFT</td>
<td colspan="4" style="padding: 0; border-bottom: solid 1px transparent;"></td>
<td rowspan="3">RIGHT</td>
</tr>
<tr>
<td> 1 </td>
<td> 2 </td>
<td> 3 </td>
<td> 4 </td>
</tr>
<tr>
<td> 5 </td>
<td> 6 </td>
<td> 7 </td>
<td> 8 </td>
</tr>
<tr>
<td> - </td>
<td> - </td>
<td> - </td>
<td> - </td>
<td> - </td>
<td> - </td>
</tr>
</tbody>
</table>

Use rowspan if you want to extend cells down and colspan to extend across.

You can use rowspan="n" on a td element to make it span n rows, and colspan="m" on a td element to make it span m columns.
Looks like your first td needs a rowspan="2" and the next td needs a colspan="4".

The property you are looking for that first td is rowspan:
http://www.angelfire.com/fl5/html-tutorial/tables/tr_code.htm
<table>
<tr><td rowspan="2"></td><td colspan='4'></td></tr>
<tr><td></td><td></td><td></td><td></td></tr>
<tr><td></td><td></td><td></td><td></td><td></td></tr>
</table>

<style type="text/css">
table { border:2px black dotted; margin: auto; width: 100%; }
tr { border: 2px red dashed; }
td { border: 1px green solid; }
</style>
<table>
<tr>
<td rowspan="2">x</td>
<td colspan="4">y</td>
</tr>
<tr>
<td>I</td>
<td>II</td>
<td>III</td>
<td>IV</td>
</tr>
<tr>
<td>nothing</td>
<td>1</td>
<td>2</td>
<td>3</td>
<td>4</td>
</tr>
</table>​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​​

I have used ngIf for one of my similar logic. it is as follows:
<table>
<tr *ngFor="let object of objectData; let i= index;">
<td *ngIf="(i%(object.rowSpan))==0" [attr.rowspan]="object.rowSpan">{{object.value}}</td>
</tr>
</table>
here,
i'm getting rowspan value from my model object.

<body>
<table>
<tr><td colspan="2" rowspan="2">1</td><td colspan="4">2</td></tr>
<tr><td>3</td><td>3</td><td>3</td><td>3</td></tr>
<tr><td colspan="2">1</td><td>3</td><td>3</td><td>3</td><td>3</td></tr>
</table>
</body>

Colspan and Rowspan
A table is divided into rows and each row is divided into cells. In some situations we need the Table Cells span across (or merged) more than one column or row. In these situations we can use Colspan or Rowspan attributes.
Colspan
The colspan attribute defines the number of columns a cell should span (or merge) horizontally. That is, you want to merge two or more Cells in a row into a single Cell.
<td colspan=2 >
How to colspan ?
<html>
<body >
<table border=1 >
<tr>
<td colspan=2 >
Merged
</td>
</tr>
<tr>
<td>
Third Cell
</td>
<td>
Forth Cell
</td>
</tr>
</table>
</body>
</html>
Rowspan
The rowspan attribute specifies the number of rows a cell should span vertically. That is , you want to merge two or more Cells in the same column as a single Cell vertically.
<td rowspan=2 >
How to Rowspan ?
<html>
<body >
<table border=1 >
<tr>
<td>
First Cell
</td>
<td rowspan=2 >

</tr>
<tr>
<td valign=middle>
Third Cell
</td>
</tr>
</table>
</body>
</html>

It is similar to your table
<table border=1 width=50%>
<tr>
<td rowspan="2">x</td>
<td colspan="4">y</td>
</tr>
<tr>
<td bgcolor=#FFFF00 >I</td>
<td>II</td>
<td bgcolor=#FFFF00>III</td>
<td>IV</td>
</tr>
<tr>
<td>empty</td>
<td bgcolor=#FFFF00>1</td>
<td>2</td>
<td bgcolor=#FFFF00>3</td>
<td>4</td>
</tr>
