Jquery数据表分组插件-一种两级分组可扩展的方法？

关于jquery datatables rowgrouping插件：，是否可以有两级分组，并且两个分组都可以展开/折叠？我在网站上找不到任何提到这一点的东西。。想知道是否有人尝试过它

我也没有看到关于插件这样做的任何信息。我认为最有效的解决方案（就运行时而言）是修改rowGrouping插件本身，但这可能会在每次创建者更新插件时变得复杂（据我所知，扩展jQuery插件是不可能的）

不管怎样，我想出了一个解决办法。它并不漂亮，而且可能需要很多改进，但希望它至少能激发一些想法。基本上，我创建了自己的jQuery插件来包装行分组插件（您也可以单独使用中间部分-请参阅代码中的注释）。它实例化一个rowGrouping数据表，然后遍历行，在每个主组中查找子组行。然后，它在每个子组下查找行，并为它们分配一个组/子组组合所特有的类。最后，它使用该类作为选择器，在单击子组行时切换行

// create our own jQuery plugin that wraps rowGrouping
(function ($) {
    $.fn.rowGroupingWithColapsableSecondLevel = function (options) {
        return this.each(function (index, elem) {
            // construct a rowGrouping object
            var oTableGrouped = $(elem).dataTable().rowGrouping(options);

            // subgroup row/tds are not uniquely identified
            // find each group row (identified by it's td having the class .group) and identify it (via a unique class per subgroup) and bind a click to the subgroup row that will toggle this class

            // SIDE NOTE: if you don't want to use the plugin wrapping method, just isolate the following "find" block and replace oTableGroup with a reference to the table object (or create an object or function with the find block)
            // example: var myTable = $('#example').dataTable().rowGrouping(); // then use myTable.find... below

            oTableGrouped.find('tbody tr td.group').each(function(index, elem) {
                var groupName = $(elem).attr('rel'); // e.g., group-1
                var tr = $(elem).parent();
                var subgroupId = 0; // incremental Id within group

                // go through subsequent rows looking for subgroups until we hit another major group (or run out of rows)
                do {
                    var tr = tr.next('tr'); // get the next row
                    if (tr.find('td').hasClass('subgroup')) {
                        // this is a subgroup row
                        subgroupId ++;
                        // give this subgroup an id so we can work with it
                        tr.attr('id', groupName + '-subgroup-' + subgroupId);
                        // assign parent group id as class so it will be toggled with other rows
                        tr.addClass('group-item-' + groupName);
                        // assign a toggle function
                        tr.click( function() {
                            $('.' + $(this).attr('id')).toggle();
                        });
                    } else if(tr.find('td').hasClass('group')) {
                        // we've reached the next group, exit the do loop (the next group will be picked up by the next oTableGroup.find)
                        break;
                    } else if(tr.length == 1) {
                        // this is a row under the subgroup, identify it by adding a class
                        tr.addClass(groupName + '-subgroup-' + subgroupId);
                    }
                } while (tr.length == 1);
            }); // end of the find block

            return oTableGrouped;
        })
    };
})(jQuery);

下面是您将如何使用它：

$(function() {
    var oTable = $('#example').dataTable({ "bLengthChange": false, "bPaginate": false}).rowGroupingWithColapsableSecondLevel({  "iGroupingColumnIndex2": 1 , "bExpandableGrouping": true });
});

希望这有帮助。干杯。

将这两个布尔值设置为真：

bExpandableGrouping: true
bExpandableGrouping2: true

SUBSUBID的初始化应在每次调用之前进行

var subgroupId = 0; // incremental Id within group
oTableGrouped.find('tbody tr td.group').each(function(index, elem) {
