一、实现思路
二、实现
1.引入js
2.数据处理。
3.合并行，根据vxe-table的span-method方法做合并行和列
4.点击导出按钮，调用导出方法
vue项目里面的一个需求，需要导出一个excel表格，数据源是后端返回的json，需要前端处理后，由前端导出。表格样式如下。
一、实现思路
使用传统的jquery.table2excel.js js导出excel搭配vxe-table的合并单元格功能实现。
jquery.table2excel.js导出ecxel已经很成熟了。但是需求里面合并行和合并列是根据json动态变化的，使用vxe-table将表格功能都实现后，再导出即可。
二、实现
1.引入js
将jquery.table2excel2.js 和 tableExport.js 放static文件夹下（jquery.js要同时引入）query.table2excel2.js:
/* 调用方法:
* $('#test_table').table2excel2({//'#test_table' table的id
* subtotal: 1,//可选参数(可删除此行),默认值:0
* width:200,//导出excel表格的宽度百分比的值(不含%号),可删除此行(默认100%)
* filename: 'excel_' + new Date().getTime() + '.xls', //excel文件名称,扩展名:.xlsx 或者.xls
* });
*/

<script src="<%= BASE_URL %>static/jquery.table2excel2.js"></script>
<script src="<%= BASE_URL %>static/tableExport.js"></script>2.数据处理。
先要把json数据处理成一行一行的表格数据，然后再做合并行。
未合并之前把数据处理成这样展示即可，根据后端返回的json自行处理
3.合并行，根据vxe-table的span-method方法做合并行和列
html：
注意：表格要使用<table id="excelTable"></table>包起来，后面导出使用
<table id="excelTable">
<vxe-table id="excelTable" class="titleTable" height="auto" resizable ref="xTable" align="center" :print-config="{}" :column-config="{ width: 90 }" border="true" :span-method="mergeRowMethod" :data="mergeTableData">
<vxe-table-column field="indexNum" title="序号" width="25"></vxe-table-column>
<vxe-table-column field="projectName" title="项目名称"></vxe-table-column>
<vxe-table-column field="annualGoals" title="年度目标"></vxe-table-column>
<vxe-table-colgroup title="项目进展">
<vxe-table-column field="nodeName" title="节点任务"></vxe-table-column>
<vxe-table-column field="planTimeStr" title="计划完成时间"></vxe-table-column>
<vxe-table-column field="expectTimeStr" title="实际完成时间"></vxe-table-column>
</vxe-table-colgroup>
<vxe-table-colgroup>
<template v-slot:header>
<span>{{mapYears}}xxx </span>
</template>
<vxe-table-column field="totalMoney" title="目标总额"></vxe-table-column>
<vxe-table-column field="expendMoney" title="已拨付"></vxe-table-column>
<vxe-table-column field="surplusMoney" title="余额"></vxe-table-column>
<!-- <vxe-table-column field="nodeAction" title="攻坚节点动作"></vxe-table-column>
<vxe-table-column field="responsibleUnit" title="攻坚节点责任单位"></vxe-table-column>
<vxe-table-column field="responsiblePersonnel" title="主责人员（可执行动作数，有前置条件动作数）"></vxe-table-column> -->
</vxe-table-colgroup>
</vxe-table>
</table>js：关键代码
mergeRowMethod({
row,
_rowIndex,
column,
visibleData
}) {
//横向合并规则
if (row.sumFlag) {
if (column.property == "indexNum") {
return {
rowspan: 1,
colspan: 2
}
} else if (column.property == "projectName") {
//表示这一格不要了，因为前面已经把这一格合并了
return {
rowspan: 0,
colspan: 0
}
}
}
//纵向合并规则
const fields = ['indexNum', 'projectName', 'annualGoals', "totalMoney", "expendMoney", "surplusMoney"];
const cellValue = row[column.property];
const xtmcCell = row['indexNum'];
if (fields.includes(column.property)) {
const prevRow = visibleData[_rowIndex - 1]
let nextRow = visibleData[_rowIndex + 1]
if (prevRow && prevRow[column.property] == cellValue && prevRow['indexNum'] === xtmcCell) {
return {
rowspan: 0,
colspan: 0
}
} else {
let countRowspan = 1
while (nextRow && nextRow[column.property] == cellValue && nextRow['indexNum'] == xtmcCell) {
nextRow = visibleData[++countRowspan + _rowIndex]
}
if (countRowspan > 1) {
return {
rowspan: countRowspan,
colspan: 1
}
}
}
}
},
4.点击导出按钮，调用导出方法
//导出数据
exportExcel(){
var table = $('#excelTable')
//判断表格是否存在且不为空表格
if (table && table.length) {
$(table).table2excel2({
exclude: '.hidden_input', // 不导出的class
filename: 'xxxx', // 导出的文件名
fileext: '.xls', // 文件类型
exclude_img: true, // 是否导出图片
exclude_links: false, // 是否导出超链接
exclude_inputs: true, // 是否导出输入框中的内容
preserveColors: false, // 是否导出背景颜色
})
that.$message.success('导出成功!')
}
}
