    $.get("GetWorkItem.ashx", {}, function (data) {
            var obj = JSON.parse(data);
            $.each(obj.Tables, function (index, table) {
                //根据不同的表名，显示不同的字段。得到特定表，table = obj.Tables[1]
                var tableName = table.Name;
                var i = 0;
                $.each(table.Rows, function (index, row) {
                    if (tableName == "WorkItem")
                        time_day.push('<tr id="' + index + '" class="time-row">');
                        time_day.push('<td rowspan="2" class="time-title"></td>');                        for (var j = 0; j < 7; j++) {
                            time_day.push('<td class="timeItem"></td>');
                        }
                        time_day.push('</tr>');
                        table_time.push(time_day.join(''));
//                        $("#data").val($("#data").val() + row.System_Id + "\r\n");
                        $("td.time-title").each(function () {
                            var time;
                            if (i == index) {
                                time = row.System_Id;
                            } 
                            $(this).text(time);
                            i++;
                        });
