7372 * Sorting plug-in methods - Sorting in DataTables is based on the detected type of the | |
7373 * data column (you can add your own type detection functions, or override automatic | |
7374 * detection using sType). With this specific type given to the column, DataTables will | |
7375 * apply the required sort from the functions in the object. Each sort type must provide | |
7376 * two mandatory methods, one each for ascending and descending sorting, and can optionally | |
7377 * provide a pre-formatting method that will help speed up sorting by allowing DataTables | |
7378 * to pre-format the sort data only once (rather than every time the actual sort functions | |
7379 * are run). The two sorting functions are typical Javascript sort methods: | |
7380 * <ul> | |
7381 * <li> | |
7382 * Function input parameters: | |
7383 * <ul> | |
7384 * <li>{*} Data to compare to the second parameter</li> | |
7385 * <li>{*} Data to compare to the first parameter</li> | |
7386 * </ul> | |
7387 * </li> | |
7388 * <li> | |
7389 * Function return: | |
7390 * <ul> | |
7391 * <li>{int} Sorting match: <0 if first parameter should be sorted lower than | |
7392 * the second parameter, ===0 if the two parameters are equal and >0 if | |
7393 * the first parameter should be sorted height than the second parameter.</li> | |

10073 * data source.</li> | |

10075 * by default, so you will need to specify the default content you want - | |
10076 * typically an empty string). This can be useful on generated columns such | |
10077 * as edit / delete action columns.</li> | |
10078 * <li>function - the function given will be executed whenever DataTables | |
10079 * needs to set or get the data for a cell in the column. The function | |
10080 * takes three parameters: | |
10081 * <ul> | |
10082 * <li>{array|object} The data source for the row</li> | |
10083 * <li>{string} The type call data requested - this will be 'set' when | |
10084 * setting data or 'filter', 'display', 'type', 'sort' or undefined when | |
10085 * gathering data. Note that when <i>undefined</i> is given for the type | |
10086 * DataTables expects to get the raw data for the object back</li> | |
10087 * <li>{*} Data to set when the second parameter is 'set'.</li> | |
10088 * </ul> | |

10093 * | |
10094 * Note that prior to DataTables 1.9.2 mData was called mDataProp. The name change | |
