table-layout
This property controls the algorithm used to lay out the table cells, rows, and columns. A value of fixed uses the fixed table layout algorithm, which relays not the content of the cells but simply the width of the tables, columns, borders, and defined cell spacing. This should result in faster page rendering. The default value of auto uses the standard automatic table layout algorithm, which may require multiple passes or take perceptible time to calculate, particularly when the table is complex or heavily nested.
Example
table {table-layout: fixed;}
