I haven't built a "proper" table for my DP, but I do have one of those XY tables for small mills installed. Very handy for positioning and with the "T" slots, I can have a fence mounted on the back edge. I'll use the front/back position adjustment for the table to position the bit the needed distance in and just slide the work piece left/right as needed for drilling. The typical range of movement for these small tables is somewhat limited.
