To Update a Hole Table
If you have changed the holes, cuts, datum points, or datum axes in the model, or if you want to revert any modified hole table values to the accurate model values, you must update the corresponding hole tables.
On the Table tab, click Update Tables. Alternatively, right-click and click Update Tables on the shortcut menu. All the tables in the active drawing including the hole tables are updated with the most recent model information.

You can modify the hole table cells as you would do to a normal table.
