SpreadJS 生成报表

空了再写个完整的demo吧

//报表控件 输入参数待定
function SpreadObj(response) {

    var spread = null;

    //数据列表
    var dataArray = [
      ["位置", '至上期末位移值（mm）', '本期位移（mm）','至本期末位移(mm)', '最大位移量（mm）', '位移速率（mm/月）', '预警值（mm）', '控制值（mm）'],
    ];

    //数据列表信息 端点坐标
    var dataListInfo = {
        x: 0,//顶点坐标（左上角） x
        y: 4,//顶点坐标（左上角） y
        rows: 5,//行数
        cols: 7//列数
    };

    //基本信息
    var baseInfo = {
        reportName: '',
        reportNum: '',
        bridgeName: '',
        monitorUnit: '',
        monitorDate: ''
    };

    //加载控件
    function loadSpread() {
        InitBaseInfo();

        spread = new GC.Spread.Sheets.Workbook(document.getElementById("ss"), {
            sheetCount: 1
        });
        initSpread(spread);//初始化
        //bindEvent(spread);//加载按钮事件
        switchRowColumn(spread);
    }
