Users could set a fixed width for a column directly in Standard tab of Column section. To make the column expand or shrink as the screen size changes, you can set the relative width for table column.
1 Click the table and in Appearance tab, set the width to any kind except Auto Size.
Note If you set the table as Auto Size, the width of table column cannot be relative.
2 In Columns tab, select % as width unit and input the number for the column.
