Columm.width (table a) == columm.width (table b)

[Jerome]

Hi,

When I have 2 tables with the same amount of columms like:

<table id="a"><tr><td id="1"></td><td id="2"></td></tr></table>

and

<table id="b"><tr><td id="3"></td><td id="4"></td></tr></table>

How can I define that the first columm from both tables has the same width, so the width of columm id:1 and id:3 is the same.

Important remark: i can not define an actuall width, like 30% or 200px to the columm, the width depends on the data generated and placed in columm id:1

thead, tbody and tfoot are no option either.

Thanks for your effort,
Jerome

Sorry but with the list of things you say you can't do, the thing you want to do is eliminated as an option as well.

Hmmm,

Should it be possible to get width of id1 like

var howwidth=document.getElementById('id1').style.width;

and apply it to id3, like:

document.getElementById('id1').style.width=howwidth;

Or is this a weird approuce?
