Inventor Drawing Tables (Parts Lists, General Tables, Revision Tables) don't seem to have the standard connection grips that a user would expect them to have. As a result, tables don't snap to other tables, or other drawing resource elements such as a sketched symbol. Note on the below screenshot, how the sketched symbols snap to both the Drawing Boarder and also other Sketched Symbols via their Connection Grips, yet it's impossible to snap the Sketched Symbols to Tables in the drawings, or tables to each other;
Users should at least be given the option to right click a drawing table to toggle "Connection Grips" on & off as they require.
