请参阅下面的代码。我想从xlsx文件中读取数据，工作表名称为： WPA ext libs 2017.10.05 。现在我想读取第一列的值。我应该在下面的代码中做些什么改变？

var Excel = require("exceljs");

var workbook = new Excel.Workbook();
workbook.xlsx.readFile("./CIoT_External Libraries & 3rd Party Content.xlsx")
.then(function(data){
    var worksheet = workbook.getWorksheet("WPA ext libs 2017.10.05");

使用exceljs循环浏览excel文件的最佳方法是使用内置方法.eachRow（）

var Excel = require("exceljs");
var workbook = new Excel.Workbook();
workbook.xlsx.readFile("./CIoT_External Libraries & 3rd Party Content.xlsx" )
.then(function(data){
    var worksheet = workbook.getWorksheet("WPA ext libs 2017.10.05");

    worksheet.eachRow(function (row, rowNumber){
        // row_values contains the values, (first column is indexed by  
        var row_values = row_1.values;
        // Now you can access the columns directly by the column index
        Console.log("Value of Column B is : "+ row_values[2])
    }
 });
