對應(yīng)導(dǎo)出按鈕綁定事件函數(shù)如下:

function exportData() {
  const headerStrList = ['姓名', '年紀(jì)', '性別'];
  const dataArr = [];
  this.tableData.forEach(item => {
  const arr = [item.name, item.age, item.gender];
  dataArr.push(arr);  
  }
  const excelList = [];
  excelList.push(headerStrList.join('\t,') + '\n');
  dataArr.forEach(item => {
    excelList.push(item.join('\t,') + '\n');
  })
  const exportStr = excelList.join('');
  const uri = 'data:text/csv;charset=utf-8,\ufeff' + encodeURIComponent(exportStr);
  const link = document.createElement('a');
  link.href = uri;
  link.download = '下載表格數(shù)據(jù).csv';
  link.click();
}
//notice:不想要csv格式的數(shù)據(jù)，將下載文件的文件名后綴改成xlsx也可以
