title: Fast selection of table columns with jQuery
body: <p>We have a large HTML table (maybe 100x100 cells). Selecting rows is pretty fast as we can simply select all TDs in a specific TR. But selecting columns with the help of jQuery and <code>nth-child</code> is much slower. Are there any faster alternatives for column selection? How about pseudo classes for every column (like class="column-1", and so on)? What is your experience with this?</p>
