Call TableCellRenderer after every setValueAt().

Question

I've made a TableCellRenderer which colours some cells depending on some values. My only problem is, that it only colours the cells after a addRow() or similar and not after every setValueAt().
I want my table to colour the cells after every change in the table.
How is this possible?

Since I don't know how you have implemented your Table Model I can't be sure of the detail but if you have extended DefaultTableModel or AbstractTableModel then in method setvalueAt() you call fireTableCellUpdated() with whatever row and col you are updating. Something like
public void setValueAt(int row, int col)
    // do your stuff to update the value
    fireTableCellUpdated(row, col);)
}
