Hi, Branch,
Those testimonials tables can be tricky since they contain lots of cells to hold the images that create the style. One thing I would do is remove the height from the tables. The content should decide the height, not the height attribute. Also try re-sizing the table by taking the bottom right corner and dragging the corner towards the center of the table. This will affect the width, but that's easily adjusted once the cells close up properly.
To add a proper break between tables, images, videos, etc., use <br clear="all"> instead of <p> </p>.
If all else fails, feel free to email me your template and I'll sort out the problem for you (
