When we use a table in Word, we often need to enter a number in the first column of the table to better reflect the order of the contents in the table. However, if you enter these serial numbers manually, sometimes deleting a row of useless data will inevitably cause the column ordinal to be re-enter. In fact, with the "Bullets and numbering" feature of the word software, it's easy to adjust the column number automatically as the number of rows changes.
After you have created the table, select the column that you want to enter the ordinal number.

Click Bullets and Numbering on the Format menu, and under the Numbering tab in the Bullets and Numbering window that pops up, select the appropriate number type and click OK.

At this point, the column you just selected will automatically appear in the sequence number. If you delete a row, the number of subsequent rows is automatically elevated to fit the continuity of the serial number, and no longer requires us to manually modify it.
