帆软预览中有数据,但是点击导出excel后打开excel数据有几列变成了0,其它的正常,怎么解决?js脚本如下:var dt = this.options.form.getWidgetByName("BUSI_DATE").getValue();var dt2 = this.options.form.getWidgetByName("LAST_YEAR_DATE").getValue();var y = dt.slice(0, 4);var m = dt.slice(4, 6);var d = dt.slice(6, 8);var name = "xxx" + y + m + d;var REPORT_URL = '/webroot/decision/view/report?viewlet=abc/xxx.cpt&format=excel&extype=simple&isExcel2003=true&LAST_YEAR_DATE=' + dt2 + '&BUSI_DATE=' + dt + '&__filename__=' + name;window.location = (FR.cjkEncode(REPORT_URL));
