how to set the padding-left property of a specific column in a celltable?

[tong123123]

I try to use css

.iconColumn{
  padding-left:2px;
}

and then in gwt, write

Column.setCellStyleNames("iconColumn");

but I found no effect on the specific column left padding!!

[tong123123]

the column is inside a table with css class name "ellipsis", so  I try to change
.ellipsis .iconColumn{
  padding-left:2px;
  padding-right:2px;

}

and then in gwt, write
Column.setCellStyleNames("

iconColumn");

very strange, padding-left is in effect now, but now padding -right!! in IE, if I press F12 and change the td padding-left property, the layout will change, but if I change the padding-right property, nothing changed!!

Try

.iconColumn {
padding-left: 2px !important;
}
