If you use tables (not for layout, of course) it can be very tedious to get the borders to surround every cell using CSS. You need to set the border on the table and on every
td, and then collapse the borders with
border-collapse. I don’t know about you, but I would often just add the
border attribute to the table, just to get it done quickly.
Well, this week the HTML5 working group decided to make that okay again. They agreed that many tables need to have borders to define the cells. The proposal pointed out that putting CSS on a table to define the borders would not be carried over when the table was moved between implementations. In other words, if you wrote a table in an HTML document, and then ported that document into XML, the borders in CSS would stay with the CSS, not with the table.
Now it is legal to write <table border> to add borders around your table and table cells. I, for one, am pleased!
