电子表格单元格中使用计算公式，导出为excel文件不显示公式只显示计算结果

function main(spreadsheetReport) { 
    var sheetIndex = 0; 
    var posList = spreadsheetReport.sheets[sheetIndex].getExpandedPositions("E1"); //获取E1扩展后的单元格列表 
    var cells = spreadsheetReport.workbook.worksheets.get(sheetIndex).cells; 
    for (var i = 0; i < posList.length; i++) { 
    	var cell = cells.get(posList[i].row, posList[i].column); 
     	var value = cell.getValue(); //获取单元格值 
      	cell.setFormula(""); //清除公式 
       	cell.setValue(value); //重新设置单元格值 
        } 
}

function main(spreadsheetReport) {
    var type = spreadsheetReport.outputType; //导出类型
    if (type == "EXCEL2007" || type == "LIST_EXCEL") {
        spreadsheetReport.cacheable = false;
        var workbook = spreadsheetReport.workbook; //获取电子表格工作簿
        var worksheets = workbook.worksheets;
        for (var i = 0; i < worksheets.count; i++) {
            var worksheet = worksheets.get(i); //sheet1
            var cells = worksheet.cells;
            var maxDisplayRange = cells.maxDisplayRange; //表格最大范围
            //对表格中的值进行循环判断
            for (var x = 0; x < maxDisplayRange.rowCount; x++) {
                for (var y = 0; y < maxDisplayRange.columnCount; y++) {
                    var cell = cells.get(x, y);
                    if (cell.isFormula()) {
                        cell.value = cell.value;
                    }
                }
            }
        }
    }
