Here's how I have solved this issue:
1. Include the column in the grid.
2. Make the column heading blank.
3. Make the text in the column white.
4. Make the column as narrow as you can.
5. For the header and the data, turn off the right-hand border for the column.
6. For the column to the left, turn off the left-hand border for the header and the data.
This makes the data in the column disappear and makes it so that the column "hides" as part of another column.
