使用以下的 renderer和合适的format 以及你喜欢的 allignment.

Make sure to set it on the coloms where it's required with something like this:

yourTable.setDefaultRenderer(Integer.class, new TableCellRendererSimple(integerFormat, JTextField.TRAILING))

Where integerFormat is for instance a DecimalFormat instance.


/**
* TableCellRenderer.
* 
* @author Rene Peters
* @version 1.0 15-dec-2003
*/
public class TableCellRendererSimple extends DefaultTableCellRenderer {

Format format = null;

public TableCellRendererSimple(Format format, int allignment) {
super();
this.format = format;
this.setHorizontalAlignment(allignment);
}

public void setValue(Object value) {
if (format == null) {
setText((value == null) ? "" : value.toString());
} else {
setText((value == null) ? "" : format.format(value));
}
}
}

Change the JTextField.TRAILING into LEFT, RIGHT, CENTER for your own requirement.
