table cell alignment problems video shortcode

I have a table with 2 rows and 2 columns.

When I place the video shortcode into each cell and align each cell vertical to TOP all but one video aligns properly.

so the first two (horizontally)do not line up. Instead the second video is kicked down about 10px.

The bottom 2 align horizontally to the top properly.

It’s almost as if in the first row the second video has a top padding of 10px but it does not.

All the cells are formatted exactly the same. I even copied and pasted the same video shortcode in all cells, so all the html is the same.

I have looked at the code for some difference but it’s all the same for each cell, no hidden breaks or returns etc

I know maybe I should use divs but I does anyone know why this happens?

Thanks,
