Hi !

I'm writing swing application that shall compare differences between
objects. I have a jTable, and its every row represents one entity. In
database i have corresponding states of that object and it is possible
to show differences between these states in table cells. I have my own
table model

    public Object getValueAt(int rowNumber, int columnNumber) {
        if (rowNumber < 0 || rowNumber >= getRowCount())
            return "";

        Object obj = objectList.get(rowNumber);

        switch (columnNumber) {
                       ....
            case 2:
                return obj.getSomeValue()
                       ...
                       case x:
                              return new
ComparableValues(obj.getSomValue(), value to compare with);
              }
   }

I also have specific TableCellRenderer attached to column, it acts
like this

class MyCellRenderer extends DefaultTableCellRenderer {

    public Component getTableCellRendererComponent(JTable table, Object
value, boolean isSelected, boolean hasFocus, int row, int column) {
            Component cell = super.getTableCellRendererComponent(table, value,
isSelected, hasFocus, row, column);

            if (value instanceof ComparableValues) {
                               // cast
                               setText("(" + value.getDifference() +
" )" + value.getOriginalValue())
                       }
       }
}

Everything works great, but i would like to improve cell design ...

Q1) How to use more than one text color in cell ?
Q2) How to use many font sizes in one cell ?

I have one idea but i don't like it ;) (MyTableCellRendere extends
JLabel and use html as a content ... )

in advance, thx for any help
