HTML: how to use colspan and rowspan? - html

I am trying to build a very simple array, but somehow It is not working How I think it should. Here is an example:
<!DOCTYPE html>
<html>
<head>
<style>
table, th, td {
border: 1px solid black;
}
</style>
</head>
<body>
<table width=100%>
<tr>
<th colspan="8">sigle row of 8 cols</th>
</tr>
<tr >
<td colspan="2">2 cols </td>
<td rowspan="3" colspan="6" > 6 cols</td>
</tr>
<tr>
<td colspan="2">2 cols</td>
</tr>
<tr>
<td colspan="2">2 cols</td>
</tr>
</table>
</body>
</html>
Please help me to debug.
I want the months to occupy only 2 column and the saving to occupy 6 columns (the rest), but, this is not working as expected. I know the answer is trivial, but I cannot find it. Can you please tell me what is wrong?


The table will have 8 columns, but you have effectively reduced it to 2. The table rendering algorithm will make things as efficient as it can.
By adding an additional row you can see what is happening
<!DOCTYPE html>
<html>
<head>
<style>
table, th, td {
border: 1px solid black;
}
</style>
</head>
<body>
<table width=100%>
<tr>
<th colspan="8">Monthly Savings</th>
</tr>
<tr >
<td colspan="2">January</td>
<td rowspan="3" colspan="6" >$30000</td>
</tr>
<tr>
<td colspan="2">February</td>
</tr>
<tr>
<td colspan="2">March</td>
</tr>
<tr>
<td>1</td>
<td>2</td>
<td>3</td>
<td>4</td>
<td>5</td>
<td>6</td>
<td>7</td>
<td>8</td>
</tr>
</table>
</body>
</html>
What you are better off doing is assigning width to the columns
table, th, td {
border: 1px solid black;
}
<table width=100%>
<tr>
<th colspan="2">Monthly Savings</th>
</tr>
<tr >
<td style="width:33%">January</td>
<td rowspan="3" style="width:66%" >$30000</td>
</tr>
<tr>
<td>February</td>
</tr>
<tr>
<td>March</td>
</tr>
</table>


because the you add heading in single <th> so make id different
<th colspan="2">Monthly</th>
<th colspan="6">Savings</th>
so it will display 2 for month and 6 for saving
<!DOCTYPE html>
<html>
<head>
<style>
table,
th,
td {
border: 1px solid black;
}
</style>
</head>
<body>
<table width=100%>
<tr>
<th colspan="2">Monthly</th>
<th colspan="6">Savings</th>
</tr>
<tr>
<td colspan="2">January</td>
<td rowspan="3" colspan="6">$30000</td>
</tr>
<tr>
<td colspan="2">February</td>
</tr>
<tr>
<td colspan="2">March</td>
</tr>
</table>
</body>
</html>

How to position a table in right side of screen using HTML?

How to position a table on the right side of the screen? The desired output looks like this:
table on the right
How do we pull it off? Thanks!
The code I used is:
<!DOCTYPE html>
<html>
<head>
<style>
table,
th,
td {
border: 1px solid black;
}
</style>
</head>
<body>
<table>
<tr>
<td colspan="2">Sum: $180</td>
</tr>
<tr>
<th>Month</th>
<th>Savings</th>
</tr>
<tr>
<td>January</td>
<td>$100</td>
</tr>
<tr>
<td>February</td>
<td>$80</td>
</tr>
</table>
</body>
</html>

sometimes reading documentation may be useful
table,
th,
td {
border: 1px solid black;
}
table {
float: right;
}
<table>
<tr>
<td colspan="2">Sum: $180</td>
</tr>
<tr>
<th>Month</th>
<th>Savings</th>
</tr>
<tr>
<td>January</td>
<td>$100</td>
</tr>
<tr>
<td>February</td>
<td>$80</td>
</tr>
</table>

You can make the table right side by using following code:
table{
width: auto;
float: right;
}
table {
width: auto;
float: right;
}
<html>
<body>
<table>
<tr>
<td>
Item 1
</td>
<td>
Item 2
</td>
</tr>
</table>
</body>
</html>

The needed code to pull it off is:
<!DOCTYPE html>
<html>
<head>
<title>Page Title</title>
<style>
table, th, td {
border: 1px solid black;
}
table {float: right;}
</style>
</head>
<body>
<table>
<tr>
<th colspan="2">Ouch</th>
</tr>
<tr>
<th colspan="2"><img src=AAAAAHjpg" alt="Posporo" width="300" height="300"></th>
</tr>
<tr>
<th colspan="2">Professional</th>
</tr>
<tr>
<th>Affiliation</th>
<td>Mafia</td>
</tr>
<tr>
<th>Profession</th>
<td>Eater</td>
</tr>
<tr>
<th>Partner</th>
<td>You</td>
</tr>
<tr>
<th>Base</th>
<td>Somewhere</td>
</tr>
<tr>
<th colspan="2">Personal</th>
</tr>
<tr>
<th>Education</th>
<td>Pamantasan ng Unibersidad ng Paaralan</td>
</tr>
<tr>
<th colspan="2">Signature</th>
</tr>
<tr>
<th colspan="2">gd jasdagjadgjd</th>
</tr>

How to custom position row table?

I want to customise my table row position like the image below. The table header should be aligned at same level but the elements inside should look like the image below.
Here's my code.
<!DOCTYPE html>
<html>
<head>
<style>
table, th, td {
border: 1px solid black;
}
</style>
</head>
<body>
<table>
<thead>
<tr>
<th>Destination</th>
<th>Speed</th>
</tr>
</thead>
<tbody>
<tr>
<td>Destination 1</td>
<td rowspan="1">5.0</td>
</tr>
<tr>
<td>Destination 2</td>
<td rowspan="1">5.0</td>
</tr>
<tr>
<td>Destination 3</td>
</tr>
</tbody>
</table>
</body>
</html>

td:not(:first-of-type) {
position: relative;
transform: translateY(50%);
}
<!DOCTYPE html>
<html>
<head>
<style>
table, th, td {
border: 1px solid black;
}
</style>
</head>
<body>
<table>
<thead>
<tr>
<th>Destination</th>
<th>Speed</th>
</tr>
</thead>
<tbody>
<tr>
<td>Destination 1</td>
<td rowspan="1">5.0</td>
</tr>
<tr>
<td>Destination 2</td>
<td rowspan="1">5.0</td>
</tr>
<tr>
<td>Destination 3</td>
</tr>
</tbody>
</table>
</body>
</html>

How do I arrange content in thead

I wan to arrange columns in my thead to look like the below image
This my code
<thead>
<tr>
<td style="text-align: center;">SUBJECT</td>
<td style="text-align: center;" colspan="3">CA<br> T1 T2 T3</td>
<td style="text-align: center;">CA TOTAL (40)</td>
<td style="text-align: center;">SIGN</td>
</tr>
</thead>
But it displays like this, how can I split the 'CA' column

You need take 2 rows for thead for display.
Here is the complete code
<!DOCTYPE html>
<html>
<head>
<style>
table, th, td {
border: 1px solid black;
border-collapse: collapse;
}
th, td {
padding: 5px;
text-align: left;
}
</style>
</head>
<body>
<table style="width:100%">
<thead>
<tr>
<td style="text-align: center;" rowspan='2'>SUBJECT</td>
<td style="text-align: center;" colspan="3">CA</td>
<td style="text-align: center;" rowspan='2'>CA TOTAL (40)</td>
<td style="text-align: center;" rowspan='2'>SIGN</td>
</tr>
<tr>
<td style="text-align: center;">T1</td>
<td style="text-align: center;">T2</td>
<td style="text-align: center;">T3</td>
</tr>
</thead>
</table>
</body>
</html>

You can't split a cell into more cells, you can only merge existing cells together. That said, if you want to have five columns you need to create five columns, and rather than using a <br> to force content to a new line in one cell, and then fake separate cells, use two rows of cells. This, of course, requires the appropriate use of the colspan and rowspan attributes, such as the following:
table {
border-collapse: collapse;
}
th,
td {
text-align: center;
border: 1px solid #000;
min-width: 4em;
min-height: 2em;
padding: 0.2em 0.5em;
}
th {
vertical-align: top;
}
<table>
<thead>
<tr>
<!-- rowspan="2" forces the following <th> element
to span two rows in its containing element: -->
<th rowspan="2">SUBJECT</th>
<th colspan="3">CA</th>
<!-- as it does here also: -->
<th rowspan="2">CA TOTAL (40)</th>
</tr>
<tr>
<!-- this <tr> contains only three <th> elements,
unlike the previous <tr> which contains five,
because two <th> elements of the previous row
will occupy space in this <tr> also -->
<th>T1</th>
<th>T2</th>
<th>T3</th>
</tr>
</thead>
<tbody>
<tr>
<td>English Language</td>
<td>3</td>
<td>6</td>
<td>10</td>
<td></td>
</tr>
<tr>
<td>Mathematics</td>
<td>3</td>
<td>5</td>
<td>7</td>
<td></td>
</tr>
</tbody>
</table>
JS Fiddle demo.
Incidentally, where possible try to style your content via the use of stylesheets; this makes it far easier to update your style and presentation in future.

<thead>
<tr>
<td style="text-align: center;" rowspan='2'>SUBJECT</td>
<td style="text-align: center;" colspan="3">CA</td>
<td style="text-align: center;" rowspan='2'>CA TOTAL (40)</td>
<td style="text-align: center;" rowspan='2'>SIGN</td>
</tr>
<tr>
<td style="text-align: center;">T1</td>
<td style="text-align: center;">T2</td>
<td style="text-align: center;">T3</td>
</tr>
</thead>

Use rowspan and 2 trs
th { vertical-align: top; border: 1px solid black;}
<table>
<thead>
<tr>
<th rowspan="2" style="text-align: center;">SUBJECT</th>
<th style="text-align: center;" colspan="3">CA</th>
<th rowspan="2" style="text-align: center;">CA TOTAL (40)</th>
</tr>
<tr>
<th>T1</th>
<th>T2</th>
<th>T3</th>
</tr>
</thead>
</table>

You can use this. Working perfectly:
<style>
table, th, td{
border: 1px solid black;
border-collapse: collapse;
}
th, td {
padding: 5px;
border: 1px solid #000;
}
</style>
<table>
<thead>
<tr>
<th rowspan="2" >SUBJECT</th>
<th colspan="3">CA</th>
<th rowspan="2">CA TOTAL (40)</th>
<th rowspan="2">SIGN</th>
</tr>
<tr>
<th>T1</th>
<th>T2</th>
<th>T3</th>
</tr>
</thead>
<tbody>
<tr>
<td>English Language</td>
<td>3</td>
<td>6</td>
<td>10</td>
<td></td>
<td></td>
</tr>
<tr>
<td>Mathematics</td>
<td>3</td>
<td>5</td>
<td>7</td>
<td></td>
<td></td>
</tr>
</tbody>

Firefox print colspan borders on second page

I have a long table that can be printed only on 2 pages. The table also has colspans in the thead section. When printing the table, borders are missing from cells where there was a colspan above.
It's probably a Firefox bug since in Chrome there's no problem. But my client uses Firefox, so I need to solve this problem somehow. I'll report this bug to Mozilla, but I wouldn't like to wait years until they fix it.
Do you know any workaround that could be used here?
This is how the table is rendered in Firefox (it has much more rows in reality)
But when I print it, some borders disappear from the second page.
Here I zoomed into the second page:
Here's my example code:
<html>
<head>
<style type="text/css">
th, td{
border-style: solid;
border-width: 1px;
border-color: black;
padding: 5px;
}
table{
border-collapse: collapse;
}
</style>
</head>
<body>

Here's what I have done:
I wrapped the content of every second cell with a div.
Then I expanded the size of the div to the cell's size. Then I used the div's border-left property instead.
CSS (less):
tbody tr>td:nth-of-type(even){
padding: 0 !important;
&>div{
padding: 2px;
position: relative;
width: 100%;
height: 100%;
margin-left: -1px;
border-left-style: solid;
border-left-width: 1px;
border-left-color: black;
}
}

Merging cells in a table doesn't work as expected

This is a table that I would like to achieve:
But I keep getting something like this:
This is what I've tried:
<table>
<tr>
<td rowspan="2">a</td>
<td colspan="2">b</td>
</tr>
<tr>
<td colspan="2">c</td>
</tr>
<tr>
<td colspan="2">d</td>
<td>e</td>
</tr>
</table>
Here's a link to JSFiddle with this (with some extra code for illustration): http://jsfiddle.net/2292D/

You need only vertical-align:middle and text-align:center
Apply this css to div
div {
display:table-cell; // Change
vertical-align:middle; //Change
border: 1px solid blue;
}
td {
border: 1px solid red;
text-align:center; // Change
}
Fiddle Demo

Good old days using table, use rowspan and colspan to achieve that kind of tablular structure, if you are using this for layout than don't, use div instead with float and CSS Positioning.
Demo
<table border="1" width="100%">
<tr>
<td rowspan="2" width="30%">a</td>
<td colspan="2">b</td>
</tr>
<tr>
<td colspan="2">c</td>
</tr>
<tr>
<td colspan="2" width="70%">d</td>
<td>e</td>
</tr>
</table>

I guess you need 3 rows for that, try my code:
<table>
<tr>
<td rowspan="2"><div id="a">a</div></td>
<td colspan="2"><div id="b">b</div></td>
</tr>
<tr>
<td colspan="2"><div id="c">c</div></td>
</tr>
<tr>
<td colspan="2"><div id="d">d</div></td>
<td><div id="e">e</div></td>
</tr>
Here's my fiddle: http://jsfiddle.net/LLe5c/

apply your id on td
html:
<table>
<tr>
<td id="a" rowspan="2"><div>a</div></td>
<td id="b" colspan="2"><div >b</div></td>
</tr>
<tr>
<td id="c" colspan="2"><div >c</div></td>
</tr>
<tr>
<td id="d" colspan="2"><div >d</div></td>
<td id="e"><div >e</div></td>
</tr>
</table>

Here is the Solution
<table>
<tr>
<td rowspan="2">a</td>
<td colspan="2">b</td>
</tr>
<tr>
<td colspan="2">c</td>
</tr>
<tr>
<td colspan="2">d</td>
<td>e</td>
</tr>
</table>
<style>
table {
border-collapse: collapse;
border-spacing: 0;
}
td {
border: 1px solid red;
}
</style>
