You need to subclass JTable and override the method getToolTipText().

JTable table = new JTable(model)
{
    public String getToolTipText(MouseEvent event)
    {
        int col  = convertColumnIndexToModel(
           columnAtPoint(event.getPoint()));
        return getColumnName(col);
    }
};

Swing uses the UIManager class to store defaults. Its put() method can be used to change these values.

// Change the default foreground color for tooltips

UIManager.put("ToolTip.foreground", Color.red);

// Change the default background color for tooltips

UIManager.put("ToolTip.background", Color.white);
