Setting the Table layout Different browsers use different methods to calculate how a particular table should be displayed. Two primary table-layout. Fixed method bases its layout on the width of the table and the width of columns in the first row. This method is generally faster than automatic. Automatic uses the table column width along with the amount of content in the table data cell to calculate the table data cell width. This will generally render more slowly than the fixed method, but it also produces more accurate results for widths throughout the table.
