一、el-table为正常时，导出方法如下：
1.添加导出按钮
<el-button class="greenLinearbg dc" size="small" @click="webExportTotalExcel()" v-if="totalBillShow">导出</el-button>
2.导出方法
// web导出汇总单excel
webExportTotalExcel(){
// 获取表格数据
//const tableData = this.userTotalList;
const tableData = this.userTotalList.map(row => { //创建一个新的数组，处理null值
return Object.keys(row).reduce((acc, key) => {
acc[key] = row[key] === null ? '' : row[key];
return acc;
}, {});
});
// 构建 Excel 文件内容
let excelContent = `<html><head><meta charset="UTF-8"></head><body><table border="1">`;
// 添加表头
excelContent += '<tr>';
for (const column of this.$refs.tableRef.columns) {
if (column.property) {
excelContent += `<th>${column.label}</th>`;
}
}
excelContent += '</tr>';
// 添加表格数据
for (const row of tableData) {
excelContent += '<tr>';
for (const column of this.$refs.tableRef.columns) {
if (column.property) {
excelContent += `<td>${row[column.property]}</td>`;
}
}
excelContent += '</tr>';
}
// 构建完整的 Excel 文件内容
excelContent += '</table></body></html>';
// 创建 Blob 对象
const blob = new Blob([excelContent], { type: 'application/vnd.ms-excel' });
// 创建链接并触发下载
const link = document.createElement("a");
link.href = URL.createObjectURL(blob);
link.download = '汇总单.xlsx'; // 设置默认文件名
link.style.display = "none";
document.body.appendChild(link);
link.click();
window.URL.revokeObjectURL(link.href);
},
二、el-table中列为循环数据时，如下图所示：
导出方法如下：
1.导出按钮：
<el-button class="greenLinearbg dc" size="small" @click="webExportHistoryExcel('','历史账单','el-table__fixed-right',0,'message')" v-if="historyBillShow">导出</el-button>
2.导出方法为：
// web导出历史账单excel
webExportHistoryExcel(id,excelName,className,number=0){
const loading = this.$loading({
lock: true,
text: '数据导出中',
spinner: 'el-icon-loading',
background: 'rgba(0, 0, 0, 0.7)'
});
const columns = this.$refs.message.columns,outputColumns=[];
for(let i=0,len=columns.length;i<len;i++){
if('label' in columns[i]){
if('prop' in columns[i])
outputColumns.push(columns[i].prop);
else if('slot' in columns[i] && columns[i].slot!='action' && columns[i].label!='操作')
outputColumns.push(columns[i].slot);
}
}
if(this.$refs.message.selectRow=='all'){
request({
url:'/system/nonResidentYhzd/selectYhzdTable',
method:'post',
data:{pageNum:1,pageSize:this.queryParams.total}
}).then(response => {
ExportUtils.exportExcel(id,excelName,'',className,number,this.$refs.message.selectRow,response.rows,outputColumns);
loading.close();
});
}
else{
ExportUtils.exportExcel(id,excelName,'',className,number,this.$refs.message.selectRow,this.$refs.message.selectList,outputColumns);
loading.close();
}
},
