How do you change width of selected column to automatically fit the widest entry in the column?

To change the width of a selected column to automatically fit the widest entry in programs like Microsoft Excel, you can double-click the right boundary of the column header. Alternatively, you can select the column, go to the "Home" tab, click on "Format," and then choose "AutoFit Column Width." This will adjust the column width to accommodate the longest entry in that column.
