74 * static string that DataTables knows of. The way these plug-ins work is that you create
75 * an array of the values you wish to be sorted for the column in question and then return
76 * that array. Which pre-sorting function is run here depends on the sSortDataType parameter
77 * that is used for the column (if any). This is the corollary of <i>ofnSearch</i> for sort
