This is a table that uses the tags thead, tfoot and tbody

Note that they should be used in that order. You put tfoot above tbody and the reason given is that it allows the page to render the foot before all the data for the tbody have come in.

The only attribute that HTML5 allows is apparently the border. For other thing it is recommended that you use CSS. W3schools says, "Only the "border" attribute is supported in HTML5, and it only allows the values "" or "1"".
