What I proposed above works. Put the cursor in the "Geometry" cell, 
right click, select Settings..., and in the Column settings section of 
the Table Settings tab set a fixed width for the column. That enables 
the Vertical alignment control, which you set to Middle. You might want 
to horizontally center as well; that's up to you.
I've attached a modified version of the MWE.
