How to remove empty column or row in a org table with a function

Question

When creating a table from a region, the empty column and row have to be deleted.

Answer 1

You can remove a column (empty or not) by using M-S-<left> with the cursor in the column you want to remove.

Similarly, for a row, you can use M-S-<up> with the cursor in the row that you want to remove.

Do C-h f org-table-delete-column and C-h f org-table-delete-row to find out more about these commands.

Note that M-S-<left> and M-S-<up> are context-dependent bindings: they are bound to org-shiftmetaleft and org-shiftmetaup respectively, not to org-table-delete-column (or -row) directly. Each of these functions examines the context and dispatches to the appropriate command from there.

Do C-h f org-shiftmetaleft and C-h f org-shiftmetaup to find out what they do in other contexts. E.g. the doc string of org-shiftmetaleft says:

Promote subtree or delete table column. Calls ‘org-promote-subtree’, ‘org-outdent-item-tree’, or ‘org-table-delete-column’, depending on context. See the individual commands for more information.
