Combobox with aligned Columns

I have a drop down box which shows 2 columns.
For example, “item number” (INTEGER) and “item name” (TEXT).
The number should be right aligned and the name should be left aligned.
Is this possible or is there another possibility to achieve this.

I do not know if there is a better way, but what I would do is create a calculated field that returns the integer formated and show that column.

function myIntegerFormated(){
   return utils.numberFormat(myInteger,'#,##0');
}

In a combobox you can also show html, so you can use something like this as the display value:

<html><table><td align=left width=100>yourtext</td><td align=right width=100>12345</td></table></html>

Thanks a lot, this works fine.
