I see. On the <col> element you need to use "visibility:collapse" to hide
the entire column. However browser support is pretty poor for it, seems to
only work well in Firefox.
The other thread you have linked pretty much has all information available
to solve your issue. Basically you have to show/hide each cell in a column
like the guy in the last post did with JQuery.
If the number of columns in your table is fixed and known then you could
also use the following css (example for 3 columns):
/* thead: th cells */
.hide-col-1 th:nth-of-type(1),
.hide-col-2 th:nth-of-type(2),
.hide-col-3 th:nth-of-type(3),
/* tbody/tfoot: td cells */
.hide-col-1 td:nth-of-type(1),
.hide-col-2 td:nth-of-type(2),
.hide-col-3 td:nth-of-type(3) {
display:none;
}
Then you can add/remove "hide-col-1" to the table and the corresponding
column will be hidden. Here is a jsfiddle that hides the second
column: http://jsfiddle.net/odbqq04x/
