You seemed to have uploaded a thumbnail instead of the actual image. Don't worry about stretching the tables, just post the full image. I suggest using tinypic for posting your images.
Just so you know, if you really want to make a character WAD, you are going to need to put a LOT of effort into it. One character WAD contains something around 170 frames.
I can't really tell from the image since they are way too small, but if the sprites come from an existing game (for example a sonic wad using Sonic 3 sprites), then it would not be allowed. They have to be done by yourself. If they are already done by yourself, then you are on the right path.
