I am away from my computer right now, so I can’t take a shot at modifying the original file for you at this moment. I did later publish a another similar table that uses a different approach at the parameter options (hopefully a better approach), and I released various different sizes of that newer table. The link below is to a smaller size of it. It may be more well-suited for you to tweak the parameters in that one, and then the only thing left is to modify the X ribs so that they accommodate the metal strut.
Here’s a quote from there about the improvement to the parameter approach:
Compared to my original table work , these “version 2” tables have some parameter tweaks intended to make the tables more robust for scaling as needed and to make it easier to edit the number of X ribs and number of Y spars just by editing the parameters with those names.
