IE Table fixed width

This thing with IE almost get me bold. I cannot set the width of a table property for example:

table td { width:50px; }

This won’t work only in IE7. Finally I found this blog post that give the property needed by IE7 to set the width of the table property

table-layout: fixed;

It works like a charm for me.

note: to all IE user, please use other browsers.

Replace “email address” with your own text.
