LayUI Layui Table 选中行变色及指定行变色

1. 众所周知，layui 表格只有悬浮变色，没有选中变色，恰好有这个需求，于是乎上代码

      $("body").on('click', '.layui-table-body tr ', function () {
            var data_index = $(this).attr('data-index');

            $(".layui-table-body tr").css("background","#FFFFFF");

            $(".layui-table-body tr[data-index=" + data_index + "]").css("background", "#d1c7b7");

        });

1. 既然能选中变色，那么肯定就能指定行变色，写在表格的done事件里

         done: function (res, curr, count) {
                var that = this.elem.next();
                res.data.forEach(function (item, index) {
                    if (item.is_back < 1) {
                        var tr = that.find(".layui-table-box tbody tr[data-index='" + index + "']");
                        //tr.css("background-color", "#ff5722");
                        tr.css("color", "#FF5722");
                    }
                });
            },
