I have a JXTreeTable and I have implements a custom Renderer.

So I have this code:

public class CustomTreeTableSpeseXCategoriaSpese extends JLabel implements TreeCellRenderer, TableCellRenderer {
    /**
     * 
     */
    private static final long serialVersionUID = 4842418316518803090L;
    private Font fontTotale = new Font("Verdana", Font.BOLD, 12);
    private Font fontNegativo = new Font("Verdana", Font.BOLD, 12);

    @Override
    public Component getTableCellRendererComponent(JTable table, Object value, 
            boolean isSelected, boolean hasFocus, int row, int column) {
        setOpaque(true);
        setHorizontalAlignment(SwingConstants.RIGHT);
        if (row== table.getRowCount()-1) {
            setForeground(Color.BLACK);
            setBackground( Color.RED );
            setFont(fontTotale);
        }else if(row != table.getRowCount() && column !=3){
            setForeground( Color.BLACK );
            setBackground(new Color(200, 200, 200));
            setFont(UtilitySwing.getTableFont());
        }else if(row != table.getRowCount()-1 && column ==3){
            //verifico il valore se negativo rosso
            //se positivo blu
            String valore = value.toString();
            if(valore.startsWith("-")){
                setForeground(Color.red);
                setFont(fontNegativo);
            }else{
                setForeground(Color.blue);
                setFont(fontNegativo);
            }
        }
         setText(value != null ? value.toString() : "<null>");
        return this;
    }

    public Component getTreeCellRendererComponent(JTree tree, Object value, boolean selected, boolean expanded, boolean leaf, int row, boolean hasFocus) {
        setOpaque(true);
        if (row== tree.getRowCount()-1) {
            setForeground(Color.BLACK);
            setOpaque(true);
            setBackground( Color.RED );
            setFont(fontTotale);
        }else if(row != tree.getRowCount()){
            setForeground( Color.BLACK );
            setBackground(new Color(200, 200, 200));
            setOpaque(true);
            setFont(UtilitySwing.getTableFont());
        }
         setText(value != null ? value.toString() : "<null>");
        return this;
    }
}

This is the code to create a JXTreeTable:

    public JTreeTable(){
JXTreeTable talbe = new JXTreeTable();
        talbe .setTreeTableModel(new RandomTextTreeTableModel(listaConti));
        talbe .setDefaultRenderer(Object.class, new CustomTreeTableSpeseXCategoriaSpese());
        talbe .setTreeCellRenderer(new CustomTreeTableSpeseXCategoriaSpese());
    }

If I try to run this code I can show this: enter image description here

If I try to open thi first Node I can see this: enter image description here

I want this: 1) Show the complete text 2) How you can see, from the images, I want to set background color gray at all first column. How can I fixed it?

EDIT

The post is not duplicate because in the segnalation post there is JTree but in my post, I have JXTreeTable, it is different

这可以使用org.jdesktop.swingx.decorator.HighlightPredicates

HighlightPredicate hlPred = new HighlightPredicate() {
    @Override
    public boolean isHighlighted(Component renderer,
            ComponentAdapter adapter) {
        return someCondition ? true : false;
    }
};

ColorHighlighter hl = new ColorHighlighter(hlPred, hlBgColor, hlFColor);
treeTable.addHighlighter(hl);
