Description

Returns properties of the currently selected table.
Result is false if there is not a table selected.

Note:
◼RowCount should be specified as -1 to update the properties entire table
◼If ColCount is different from the current count, cells will be added or deleted
◼GetTableProperties() requires an entire row to be selected. If there is no selection, this will occur automatically
◼You can update the table using using SetTableProperties
