+1 There are many problems with html tables (like inconsistent buggy implementations between browsers) but grids don't fix them and introduce other problems. You can't group cells in rows / columns html elements. You can't write a simple css selector for a particular cell. You can't easily refer to a whole row with a css selector. You can't do stuff like "highlight the whole row on hover" because you wouldn't have a parent element to select. Grids are for grid layouts, and with current feature set they can't replace tables.
