If you are using Coldfusion MX 8 cfgrid or the excelent Ext library and
you want to change the aligment for the column then a simple way
to do that is:

Add an style block like

 .x-grid-col-0 {text-align:center}
 .x-grid-col-1 {text-align:left}
 .x-grid-col-2 {text-align:right}

And that's all just remember to change  .x-grid-col-n change the n for the column you want to modify.
