Which Table

Is there any way to detect which Table is selected in the left hand column?

There is the 'table()' function, but that's not actually the same thing. If you are e.g. viewing one table having acessed it via a different table, table() will return the table you are viewing and not the one actually selected in the left hand column. So if using a 'dashboard' type table with 'View' elements on a form, those 'Views' will likely show records from a different table and viewing those records will set the result of the table() function to be that table set for the 'View' and NOT the dashboard table, as selected in the LH Table list.

So is it possible to determine that the records are being viewed via a dashboard type table rather than directly, within their own table as selected in the LH Table list?
