HTML Table Creation - html

I want to create a table like shown in the image using HTML. How to do?


User colspan="3" attribute if you need marge two cells into one .
w3schools
th, td {

How do I give one single data to a whole column in a HTML table?

I am trying to create a table using HTML like this:
I wrote something like this:
<table>
<caption>Bill Summary</caption>
<tr>
<th rowspan="2">Months</th>
<th colspan="3">Bills</th>
<th rowspan="2">Total</th>
</tr>
<tr>
<td>Electricity</td>
<td>Water</td>
<td>Gas</td>
<td align="center">9925</td>
</tr>
<tr>
<td>January</td>
<td>1000</td>
<td>1000</td>
<td>975</td>
</tr>
<tr>
<td>February</td>
<td>1200</td>
<td>1200</td>
<td>975</td>
</tr>
<tr>
<td>March</td>
<td>1500</td>
<td>1100</td>
<td>975</td>
</tr>
</table>
But it gives out put like this:
I need to have that one total amount aligned in the center and a border like the first table image
Thanks in Advance.

I guess you could use the rowspan attribute here as well.
table, th, td {
border: 1px solid;
border-collapse: collapse;
}
<!DOCTYPE html>
<html>
<body>
<table>
<caption>Bill Summary</caption>
<tr>
<th rowspan="2">Months</th>
<th colspan="3">Bills</th>
<th rowspan="2">Total</th>
</tr>
<tr>
<th>Electricity</th>
<th>Water</th>
<th>Gas</th>
</tr>
<tr>
<td>January</td>
<td>1000</td>
<td>1000</td>
<td>975</td>
<td rowspan="3">9925</td>
</tr>
<tr>
<td>February</td>
<td>1200</td>
<td>1200</td>
<td>975</td>
</tr>
<tr>
<td>March</td>
<td>1500</td>
<td>1100</td>
<td>975</td>
</tr>
</table>
</body>
</html>

move total value to third row and modify like this
<td align="center" style="vertical-align: middle" rowspan="3" >9925</td>

Slightly complicated HTML table with merged rows

I have the following table:
Comm Layer
Implemented By
Application
Application
Transport
OS
Internet
OS
Link
OS
Link
Hardware
<table>
<thead>
<tr>
<th>Comm Layer</th>
<th>Implemented By</th>
</tr>
</thead>
<tbody>
<tr>
<td>Application</td>
<td>Application</td>
</tr>
<tr>
<td>Transport</td>
<td>OS</td>
</tr>
<tr>
<td>Internet</td>
<td>OS</td>
</tr>
<tr>
<td>Link</td>
<td>OS</td>
</tr>
<tr>
<td>Link</td>
<td>Hardware</td>
</tr>
</tbody>
</table>
I would like to merge the two cells that say "Link" and the three cells that say "OS". I tried using the rowspan attribute in several ways but to no avail. I was able to merge either the two "Link" cells or the three "OS" cells, but not both.

In short: you cannot have a <tr> where all cells participate in a rowspan="" because that creates a zero-height row (as there's no row-specific content). I feel this is a design flaw in HTML.
One workaround is to have a zero-width column that always has non-rowspan="" cells (which are propped up with , but hidden (using visibility: hidden;, not display: none;):
(My posted code comments out the removed cells with <!--<td>OS</td>--> for illustrative purposes, obviously you can remove those in your final version)
table {
border: 1px solid #999;
border-collapse: collapse;
}
th, td {
border: 1px solid #999;
}
tr > *:nth-child(1) { visibility: hidden; }
<table>
<thead>
<tr>
<th> </th>
<th>Comm Layer</th>
<th>Jurisdiction</th>
</tr>
</thead>
<tbody>
<tr>
<td> </td>
<td>Application</td>
<td>Application</td>
</tr>
<tr>
<td> </td>
<td>Transport</td>
<td rowspan="3">OS</td>
</tr>
<tr>
<td> </td>
<td>Internet</td>
<!--<td>OS</td>-->
</tr>
<tr>
<td> </td>
<td rowspan="2">Link</td>
<!--<td>OS</td>-->
</tr>
<tr>
<td> </td>
<!--<td>Link</td>-->
<td>Hardware</td>
</tr>
</tbody>
</table>
There's probably improvements using more modern CSS techniques to enforce a minimum row height though - I've been using the technique since before I stopped using Dreamweaver in 2004.

<!-- Try this one -->
<table align="center" cellspacing="0" cellspadding=="0">
<thead>
<tr>
<th>Comm Layer</th>
<th>Jurisdiction</th>
</tr>
</thead>
<tbody>
<tr>
<td>Application</td>
<td>Application</td>
</tr>
<tr>
<td>Transport</td>
<td rowspan="2">OS</td>
</tr>
<tr>
<td>Internet</td>
</tr>
<tr>
<td rowspan="2">Link</td>
<td>OS</td>
</tr>
<tr>
<td>Hardware</td>
</tr>
</tbody>
</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>

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 >
Merged
</td>
</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>
