Word's sorting tool, often used for alphabetizing bibliographies or other text-based lists, can also sort numerical information in lists or in tables. You can even choose which column Word will use to sort the table; the standard method uses the first column to sort in ascending order, but you can select a different column if desired. Word will automatically compare the numerical values in that column and rearrange the rows, organizing the cells in the selected column by ascending order.
Open the document and click anywhere in the table that you want to sort.
Click the "Home" tab on the Ribbon.
Click the "Sort" icon, in the Paragraph group on the Ribbon. The icon displays a capital "A," a capital "Z" and a downward arrow. Clicking this icon activates the Sort dialog box.
Select "Column 1" -- or whichever column you prefer -- in the first field under the heading "Sort by."
Select "Number" under the field "Type."
Click the circle next to the option "Ascending."
Click "OK" at the bottom of the Sort dialog box.
