[css] CSS text-overflow in a table cell?

I solved this using an absolutely positioned div inside the cell (relative).

td {
    position: relative;
}
td > div {
    position: absolute;
    white-space: nowrap;
    overflow: hidden;
    text-overflow: ellipsis;
    max-width: 100%;        
}

That's it. Then you can either add a top: value to the div or vertically center it:

td > div {      
    top: 0;
    bottom: 0;
    margin: auto 0;
    height: 1.5em; // = line height 
}

To get some space on the right side, you can reduce the max-width a little.
