el-table中在嵌套一个el-table，这样数据格式就没问题了，主要就是样式
将共同的列放到一列中，通过渲染自定义表头render-header，将表头按照合适的宽度渲染出来
<el-table-column
prop="table"
label="子表"
class-name="has-child"
:render-header="renderHeader"
:width="childColumn.length * 120 + 2 + 'px'"
>
<template slot-scope="scope">
<el-table
border
:data="scope.row.details"
class="child-table"
:show-header="false"
>
<el-table-column
prop="startDate"
align="center"
label="起始日期"
width="120px"
></el-table-column>
<el-table-column
prop="endDate"
align="center"
label="结束日期"
width="120px"
></el-table-column>
<el-table-column
prop="applyDay"
align="center"

width="120px"
></el-table-column>

width="120px"
></el-table-column>
<el-table-column
prop="businessTripReason"
align="center"
label="出差事由"
width="120px"
></el-table-column>
<el-table-column
prop="returnDate"
align="center"
label="返程日期"
width="120px"
></el-table-column>
<el-table-column

width="120px"
></el-table-column>
<el-table-column

label="差补天数"
width="120px"
></el-table-column>
<el-table-column
prop="remark"
align="center"
label="备注"
width="120px"
></el-table-column>
</el-table>
</template>
</el-table-column>根据数据渲染表头
childColumn: [
{
label: "起始日期",
width: "120px",
},
{
label: "结束日期",
width: "120px",
},
{
label: "申请天数",

width: "120px",

width: "120px",
},
{

width: "120px",
},
{
label: "返程日期",
width: "120px",
},
{
label: "实际出差天数",
width: "120px",
},
{
label: "差补天数",
width: "120px",
},
{
label: "备注",
width: "120px",
},
],
/**
* @description 渲染子表
*/
renderHeader(h, { column, $index }) {
const childTable = this.childColumn.map((item) => {
return h(
"div",
{
style: {
width: item.width,
padding: "0 10px",
textAlign: "center",
flexShrink: 0,
flexGrow: 0,
},
},
item.label
);
});
return h(
"div",
{
class: ["child-head"],
},
childTable
);
},调样式，慢慢调到合适就行
.has-child {
padding: 0px !important;
// display: none;
& > .cell {
padding: 0 !important;
}
::before {
height: 0;
}
.child-table {
background-color: transparent;
.cell{
line-height: 34px;
}
}
.el-table--enable-row-hover .el-table__body tr:hover > td.el-table__cell {
background-color: transparent;
}
.el-table__body tr.current-row > td.el-table__cell,
.el-table__body tr.selection-row > td.el-table__cell {
background-color: transparent;
}
tr {
background-color: transparent;
}
.child-head {
display: flex;
}
