LibWeb: Prevent column sizing errors for html table

Previously when there was no difference between the sum of the
max and min-widths of all columns of a table, it would result in a NaN
value being set as the column's width as there was a division by 0.

This would result in 2+ column tables being reduced to only 1 column.
