+ * 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.
