Sizing Rows and Columns
When you position the pointer on the right edge of a column heading or the bottom edge of a row heading, the pointer changes to a double arrow to indicate that the row or column can be resized. Simply click and drag to resize the column or row.
If multiple rows are selected when you resize a row, all selected rows are resized as you drag a row border. Multiple columns can be resized in the same manner.
You can also set the size of a selected group of columns or rows to match the size of an existing row or column. First, select the group of rows or columns you want to resize, including the row or column whose size you want to match. Then, click the right border of the column header or the bottom border of the row whose size you want to match. The selected rows are resized to match the size of the row or column you clicked.
