The anchor cell in a table component is the cell that received the most recent mouse click. In some applications, the content of the anchor cell is automatically displayed in another larger and more convenient editing text area. 
    public void getAnchorCell(JTable table) {
        int rowIndex = table.getSelectionModel().getAnchorSelectionIndex();
        int vColIndex = table.getColumnModel().getSelectionModel()
            .getAnchorSelectionIndex();
    }
