How to update which columns exist in a table checkpoint - not just data in cells

We are using many table checkpoints in our keyword tests.
Occasionally we change the table structure so there are more or fewer columns
than in the original table checkpoint. I would like to automatically recreate
existing table checkpoints so new columns are included and old ones are removed.
 

Running a test with ‘update tables’ selected updates the *data* in the table, but not the table
structure itself. Table checkpoints fail with “Foo column not found” even if I’ve
gone to the table data editor and deselected all data values in the no-longer-existing
column.

How can I run a test and update all tables (including which
columns exist) during the test?
