+## December 2023

+### Added
+
+- de.slisson.mps.tables: tables now support a new property `column UI actions (experimental)`: This property adds actions to the MPS toolbar to add a new column above/below the current column or to delete the current column. These actions only work for simple tables that are based on rows (default: *false*).
