HTML Table: Multiple header rows and column - html

I need something like this in HTML
please click here for the layout
This is my code:
<table>
<tr>
<th colspan="2">ROW A</th>
</tr>
<tr>
<th colspan="3">ROW B1</th>
<th colspan="3">ROW B2</th>
</tr>
<tr>
<th>RB1.1</th>
<th>RB1.2</th>
<th>RB1.3</th>
<th>RB2.1</th>
<th>RB2.2</th>
<th>RB2.3</th>
</tr>
<tr>
<td>a</td>
<td>b</td>
<td>c</td>
<td>d</td>
<td>e</td>
<td>f</td>
</tr>
</table>
However, this is what I get:

What am I supposed to do?

You only need to change "ROW A" to this :
<th colspan="6">ROW A</th>
The number of columns is determined by the amount of columns in the row that has the most.
In this case, the highest number of columns of any row of the table is 6. If you want "ROW A" to be as wide as the table, you need a colspan of 6. If you want it to be half the width of the table, you would need a colspan of 3.

Accessibility: How to configure "column header" announcement?

I'm working on optimizing a website for visually impaired. I have a table on the page in the following format -
<table>
<thead>
<tr>
<th>Number</th>
<th>Name</th>
<th>Surname</th>
</tr>
</thead>
<tbody>
...
</tbody>
</table>
Currently the screen reader is announcing "row 1 col 1 number" but the expectation is that it should announce "row 1 col 1 number column header" when its a element. How can I configure it? Setting role="columnheader" is not working.
It is scope you are looking for to associate columns and rows.
scope="col" will associate a table header as a column header.
You can also associate a row header if you wish with scope="row"
<table>
<caption>My table caption - don't forget this so people know what a table is for / about</caption>
<thead>
<tr>
<th scope="col">Number</th>
<th scope="col">Name</th>
<th scope="col">Surname</th>
</tr>
</thead>
<tbody>
<tr>
<td scope="row">1</td>
<td>John</td>
<td>Smith</td>
</tr>
<tr>
<td scope="row">2</td>
<td>Mike</td>
<td>Simmons</td>
</tr>
</tbody>
</table>
See https://www.w3.org/TR/WCAG20-TECHS/H63.html for more info on this technique.
p.s. don't forget to add a <caption> to your table!

Splitting column into two columns in each row (and add headers)

I need split one field in some column, e.g
[A1] [B1] [C1] [D1] [E1]
[A2] [B2] [C2] [D2] [E2]
........
I would like transorm it to
[A1] [B1] [C1] [D1] [E1_1|E1_2]
[A2] [B2] [C2] [D2] [E2_1|E2_2]
.....
The simplified fragment of my code looks like:
<table>
<thead>
<tr>
<th>HEAD_A</th>
<th>HEAD_B</th>
<th>HEAD_C</th>
<th>HEAD_D</th>
<th>HEAD_E</th>
<th>
</tr>
</thead>
<tbody>
<tr ng-repeat="row in myCtrl.rows>
<td>A</td>
<td>B</td>
<td>C</td>
<td>D</td>
<td>E</td>
<td>F</td>
</tr>
</tbody>
</table>
The additional requirement and key is to add headers for this two columns (these two columns are nested in some field, ane are created via splitting).
Can you tell me how to do it?

Two Table but different width

I want to make table header and table data. But facing problem with width on that two tables different.
Here is the example table :
<table>
<tr>
<td>Name</td>
<td>Class</td>
<td>Phone</td>
</tr>
</table>
and the data here :
<table>
<tr>
<td>John Reise</td>
<td>Math</td>
<td>123456789</td>
<tr>
<td>Michael Sweirzgez</td>
<td>Information Technology</td>
<td>012345678910</td>
<tr>
So when I try to run the code, it will like this :
Name | Class | Phone
John Reise | Math | 123456789
If I delete the data, width will fit with table header.
I make 2 table, 1 table header and 1 table data cause I want to marquee this data. So table header will keep stay in the top.
Maybe you better use thead and tbody tags?
<table>
<thead>
<tr>
<td>Name</td>
<td>Class</td>
<td>Phone</td>
</tr>
</thead>
<tbody>
<tr>
<td>John Reise</td>
<td>Math</td>
<td>123456789</td>
</tr>
<tr>
<td>Michael Sweirzgez</td>
<td>Information Technology</td>
<td>012345678910</td>
</tr>
</tbody>
</table>

You can use thead and tbody. Here are the simple examples:

Selecting a cell in an HTML table by sibling cell value and column header

I've got an HTML table of which I cannot depend on how many rows and/or columns it will contain - so using index numbers is not possible. Here is an example of the table:
|Name|Description|Credit|Balance|
|Bob | Rent |400.00|1000.00|
|Jim | Car |100.00|4000.00|
Here is the HTML:
<table>
<thead>
<tr>
<th>Name</th>
<th>Description</th>
<th>Credit</th>
<th>Balance</th>
</tr>
</thead>
<tbody>
<tr>
<td>Bob</td>
<td>Rent</td>
<td>400.00</td>
<td>1000.00</td>
</tr>
<tr>
<td>Jim</td>
<td>Car</td>
<td>100.00</td>
<td>4000.00</td>
</tr>
</tbody>
</table>
I need to get the credit amount for which ever name I need.
Got it:
//tr[td[.="Jim"]]/td[count(ancestor::table/thead/tr/th[.="Credit"]/preceding-sibling::*)+1]

A table row was 2 columns wide and exceeded the column count established by the first row (1)

I want to validate my page but w3c keeps giving me this warning. I want to get rid of it but I can't seem to find the cause of it.
It gives me this error:
A table row was 2 columns wide and exceeded the column count established by the first row (1).
Table and CSS code:
<table>
<tr>
<td>Contact informatie</td>
<tr>
<td>Adres:</td>
<td>Jan van der Heydenstraat 61</td>
<tr>
<td>Postcode:</td>
<td>1223 BG</td>
<tr>
<td>Plaats:</td>
<td>Hilversum</td>
<tr>
<td>Email:</td>
<td>info#blabla.nl</td>
<tr>
<td>Telefoon:</td>
<td>06-31903706</td>
</tr>
</table>
table {
border:none;
padding-left:75px;}
td:first-child {
width:135px;
border:none;
text-align:left;}
td+td {
border:none;
text-align: left;}
Anyone any suggestions?
It means exactly what it says. One of the rows in your table has too many columns. Specifically, the first row has less columns that a subsequent row. But we can't do much unless you post some code.
Edit
The markup for the table is incorrect.
You only have one cell in the first row (or do what PeeHaa suggested)
You need to close off each row with </tr>
Just change this:
<tr>
<td>Contact informatie</td>
</tr>
To this:
<tr>
<td colspan="2">Contact informatie</td>
</tr>
YOu should always close you tablerows (tr): </tr>.
Final version:
<table>
<tr>
<td colspan="2">Contact informatie</td>
</tr>
<tr>
<td>Adres:</td>
<td>Jan van der Heydenstraat 61</td>
</tr>
<tr>
<td>Postcode:</td>
<td>1223 BG</td>
</tr>
<tr>
<td>Plaats:</td>
<td>Hilversum</td>
</tr>
<tr>
<td>Email:</td>
<td>info#vazcreations.nl</td>
</tr>
<tr>
<td>Telefoon:</td>
<td>06-31903706</td>
</tr>
</table>
In extension to what SimpleCoder said, if you have the first row of a table have only one column, then the futher ones can have no more then one column. If you want to get around this you need to put a table inside the cell i.e.
<td>
<table>
<tr>
<td><!-- Content here --></td>
</tr>
</table>
