Description:
When you use "select table" from within a table, the table is marked for selection. However if you press ^X (Ctrl+x), the table contents (each cell) is cut, but not the table.

Steps to Reproduce:
1. Add some table with data
2. from inside a cell select "table->select->table"
3. Press ^X

Actual Results:  
An empty table remains

Expected Results:
The table a s a whole should have been deleted


Reproducible: Always

User Profile Reset: No

Additional Info:
table->delete->table would do it, but why is this special case needed at all?
