Change the width of a column
A column width can be proportional or fixed. If you do not specify a width, the columns are equal in width, and the width is calculated based on the width of the table itself.
When you specify a value in the Proportional Width property, you are specifying its width in proportion to other columns in the same table. For example, consider a table with three columns: columns A, B and C. Column A has a proportional width setting of 1, column B has a proportional width of 2, and column C has a proportional width of 3. This means that column B is two times as wide as column A, and column C is three times as wide as column A.
When you specify a value as Fix Width, you are giving an absolute size for that column. By default, the number entered refers to points, but you can change the unit of measure by specifying the type of units used. See Unit Names.
