Locking columns or rows in a table in Word can be useful when you want to keep certain information visible while scrolling through the rest of the table. Here's how you can do it in Office XP Pro:

1. Open the Word document containing the table you want to work with.
2. Click anywhere inside the table to select it.
3. Click on the "Table" menu at the top of the screen.
4. Click on "Table Properties" from the dropdown menu.
5. In the Table Properties window, click on the "Row" or "Column" tab, depending on which one you want to lock.
6. Check the box next to "Repeat as header row at the top of each page" or "Repeat as header column at the left of each page", depending on which one you want to use.
7. Click "OK" to apply the changes.

Now, when you scroll through the table, the locked row or column will stay visible at the top or left side of the table, respectively. This can be especially helpful when working with large tables that require a lot of scrolling.
