Open my file, move the timeline to the begining,
step one step at a time, and make visible with the eyeballs the articles that arrive in the file browser,
I deleted stuff from your file I didn't need,
The first thing I did, was straighten up the table sketch to be the same as the view cube, and vertical to the window.
Then I constrained (put) the centre board sketch on the origin. The board for it, moved into place for me.
I made the Rectangular pattern of the body feature, and needing 9 boards, made it symmetric, count 9.
Sliding the handle out for about the right spacing, and the extent was close to 25 inches so made it 25 inches.
I then added the cutting square to the table octagon sketch. I then hide the octagon body, selected the 2 outside profiles in the sketch and cut the board pattern excess off / away.
You now have a choice to continue making legs and at the end making Components from the bodies if required.
Might help....
