Is there any way to set table column width dynamically per column via CSS/LESS?

What I mean is, is that if there are 4 columns to a table, the column's width would be at maximum 25% of the table's width. If it was 3 columns, then 33%. Two columns, 50%. 10 columns? 10%. The maximum width for the table is predetermined at 500px (for the sake of this example) and will always stay, at maximum, 500px. LESS is being used.
