使用ExcelJS

Question

使用ExcelJS将一系列单元格和/或整个工作表从一个Excel工作表复制到另一个工作表是否可能/是否有便利功能？

Answer 1

var sourceWorkbook= new Excel.Workbook();
var sourceWorksheet;
sourceWorkbook.xlsx.readFile("template.xlsx").then(function(){
    sourceWorksheet= sourceWorkbook.getWorksheet(1);
    var targetWorkbook = new Excel.Workbook;
    var targetSheet = targetWorkbook.addWorksheet();
    sourceWorksheet.eachRow((row, rowNumber) => {
        var newRow = targetSheet.getRow(rowNumber);
        row.eachCell((cell, colNumber) => {
            var newCell = newRow.getCell(colNumber)
            for(var prop in cell)
            {
                newCell[prop] = cell[prop];
            }
        })
   })  

这就是我对项目所做的。效果很好。

Answer 2

您可以使用ExcelJS将整个工作表从一个Excel工作表复制到另一个工作表。下面的代码可以工作

var tall = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15];
let sum = 0;

for (let i = 0; i < tall.length; i +=  2){
  sum += tall[i];
}

console.log(sum)

复制带有合并单元格的工作表

 var ws1 = workbook.getWorksheet('demo');
  let copySheet = workbook.addWorksheet('newdemo');

  copySheet.model = Object.assign(ws1.model, {
    mergeCells: ws1.model.merges
  });
  copySheet.name = 'new demo';
