new jQuery plugin: columnHover
For easier viewing some statistical output in a table, I needed a plugin to highlight the column which the mouse is hovering over. Searching the jQuery mailing list showed that there are others in need of something like this too. The solution to this was pretty simple but sadly works only on tables without colspans.
In the end I had to write my own plugin to get the support for tables with colspans and this is the result.
