How can I request the focus for a specific cell of a table?

This code does not work:

((DefaultTableCellRenderer)table.getCellRenderer(row,column)).requestFocusInWindow()
(returns false)

Btw.:

((DefaultTableCellRenderer)table.getCellRenderer(row,column)).isDisplayable()
returns false and

((DefaultTableCellRenderer)table.getCellRenderer(row,column)).isVisisble()
returns true...

Thanks in advance,
Stephan Collet

You need to set the row and column selection anchor.

jTable.getSelectionModel().setAnchorSelectionIndex(selectedRow);
jTable.getColumnModel().getSelectionModel().setAnchorSelectionIndex(selectedColumn);

A JTable is a single component (at least when it isn't editing), and the
"focus" concept does not work at a cell level since each cell is not a
child component of the table.

The nearest thing you could do is what another poster suggested - i.e.
set the cell you want as the selected cell in the table.
