More flexibility and features when working with tables
In some instances table header rows will stick to the top of the page you're viewing, making those really long tables easier to read!
Please note that table headers will not stick when your table:
Is inside a page layout or inside another table.
Has no header row or there are cells in the top row that aren't marked as headers.
Has a header column, instead of a header row, and scrolls horizontally.
Contains another table, that has its own header row.
