Thanks for the pointer, I've reported this to the appropriate development team.

Funny things in TableView :)

TableView[Table[{n, N[ZetaZero[n], 5]}, {n, 1, 100}], ItemSize -> {15, 1}, AllowedDimensions -> {2, 100}]

Scroll Down to the end and See RED boxes. Scroll Up at the beginning and see No data in the Column 2.

Regards :)

The following works. Replace cells to be deleted with "x" and press "OK", which will display a new TableView with the cells deleted. Pressing "Cancel" closes the dialog and the final data can be read from "table".

res=True;
While[res,
  res=ChoiceDialog[TableView[Dynamic[table],AllowedDimensions->{5,5}]];
  If[res,
    (table[[Sequence@@#]]=Null)&/@Position[table,"x",{2},Heads->False];
    table=Replace[table,{{Null..}->{},{x__,Null..}:>{x}},{1}];
    While[table[[-1]]==={},table=table[[;;-2]]]
    ]]

Hope it will be of use! / Hoffe es ist von Nutzen!

The first thing I tried when testing TableView was to copy data from Excel to TableView and vice versa. Unfortunately it’s not possible.

Thank you for the reply. I had hoped, I had made a mistake. In its current state, TableView[] is completely useless.
