Row and column creation controls don't work as intended

Issue found:

• Selecting rows, columns and cells do not work intuitively
• Snapshot: 43
• OS: Mac OS/ M1

How to reproduce

1. Open Model Editor
2. Open model which has data in it
3. Select a row or column or a single cell
4. See how easy it is to create rows and columns

Expected behavior

1. If a cell is selected, the row or column should no longer be selected
2. If the user clicks outside of the table, no cell, row or column should be selected.
3. If the user clicks on ESC button on keyboard, no cell, row or column should be selected.
4. If a cell is selected, the user should be able to (this is a change to previous spec, but it would make sense)
   1. Create a column on right/left, delete the column
   2. Create a row above/below, delete the row
      
      These changes should be possible through controls above the table or in the context menu
5. If a column is selected, the user should be able to
   1. Add column left/right
   2. Delete the selected column
6. If a row is selected, the user should be able to
   1. Add row above/below
   2. Delete selected row
