Table API changes & rendering fix

fixColumnHeaders is now fixRowHeaders.
columnHeaderMaxWidth is now rowHeaderWidth, and is required when fixed headers are set.

TableCell and TableHeader now take a width prop instead of maxWidth.

This also fixes a rendering bug in Chrome when using fixed headers.
