JTables - Right Aligning certain columns

Question

Hi!
Im having a major problem! I am using JTable in my prog, but Im finding them very difficult to customise. I am wanting my JTable to have certain Columns(for monetary values) right aligned, as this looks far better when dealing with currency. I have tried implementing this class on my JTable:
package accpick.overrides;
import javax.swing.*;
import javax.swing.table.*;
import java.awt.*;
class MyRenderer implements TableCellRenderer
     TableCellRenderer old_renderer;
     MyRenderer(TableCellRenderer old_renderer)     
          this.old_renderer = old_renderer;
     public Component getTableCellRendererComponent(JTable table,Object value,boolean isSelected,boolean hasFocus,int row,int column     )     
     // use the old renderer to render the cell          
     Component c = old_renderer.getTableCellRendererComponent(table,value,isSelected,hasFocus,row,column);
     if(column == 3||column == 4||column == 6)          
          //align right
     // set all other cells to normal          
     else          
          //align left
     return c;
The problem with this is that getTableCellRendererComponent() returns a Component, and Component does not seem to have a method to align, but JComponent does(setAlignmentX())
Please can someone help!!!Am i on the right track or am i going about it totally the wrong way?
THanks

Thanks everyone! Your advice got me past the compiler! But Im still having the problem of right aligning the columns! Was my code on the right path, or am i farting in the wind here?
Does anyone know of any relatively well structured way of doing this?
