I have my table marked fully with a grid using a sharpie. I first used a tailors white pencil, but I could not see it on the camera well enough. So I went over the lines with a sharpie. Its been over 3 years now, and I don't regret it one bit. It makes setting up drills easy. The main reason I did it is so I can recreate trouble shots more accurately when looking at a video of my shooting.
An alternative to the laser level is a piece of kite string pulled taught and temporarily attached to the table under tension with masking tape. Put the doughnuts under the string so they are in a straight line with the aim point on the facing of the pocket, and then remove the string. For the common perfectly in straight shot, fill in the donut holes with a sharpie, so you can remove them later (or when they fall off) and replace them exactly without the string or level again.
