If your design is not really responsive, I mean you can just need to set fixed font-size for the inner span, I think we have a clean solution like this. The idea is to set font-size of the td to 0, it will hide the text node completely:

.col[style*="display:none"] {
  display:table-cell!important;
  font-size:0;
}
.col > span {
  font-size:20px;
}
