Set background color of column

I would like to change the background color of columns that are editable, but when I do this using the classname, it also changes the background color of that column's header, which I don't want. Is there a way to highlight the td cells but not the th? This is how I currently have it:

DT column
{ "data": "UserFlag", "className": "table-cell-edit" }

CSS
.table-cell-edit{
    background-color: lightgoldenrodyellow;
}
