| If there is already a sub-table corresponding to the sub-table being inserted in the table, the existent sub-table is replaced by the new sub-table. The same is true if the sub-table being inserted is empty. In this case, the existent sub-table is removed from the input table. | If there is already a sub-table corresponding to the sub-table being inserted in the table, the existent sub-table is replaced by the new sub-table.

| - | It is not possible to insert a sub-table indexed by keys from arbitrary key columns. For example, in the example above, it is not possible to insert a sub-table corresponding to keys ''<2, 22>'', where 2 corresponds to the first column ("Key1") and 22 corresponds to the third column ("Key3"). To do this, first reorder the key columns using the [[Reorder Table Columns]] functor. | + | It is not possible to insert a sub-table indexed by keys from arbitrary key columns.
