* Sort on the 'alt' tag of images in a column. This is particularly useful if
|
|
* you have a column of images (ticks and crosses for example) and you want to
|
|
* control the sorting using the alt tag.
|
|
*
|
|
* @name Alt string
|
|
* @summary Use the `alt` attribute of an image tag as the data to sort upon.
