For a MWE, load the LyX source into a text editor and copy it here as a code example (indent by 4 spaces before copying it).
In order to achieve the desired functionality, don't use tables but fake them with bordered boxes and horizontal lines. Example:

Make sure that the border and horizontal line thicknesses and widths match up and format all like a regular document with constant width of the floating images. This way you don't hit a wall when the table is longer than one page, too.
Sample code:
#LyX 2.3 created this file. For more info see http://www.lyx.org/
