一：使用element中的方法
优点：
直接使用summary-method方法，直接，方便
缺点：
只是在表格下面添加了一行，如果想有多行就不行了
1：html部分
html
<el-table
v-loading="loading"
:data="tableData"
:border="true"
style="width: 100%;"
:header-cell-style="{textAlign:'center'}"
:cell-style="{textAlign:'center'}"
show-summary
:summary-method="tableHeJi"
:default-sort = "{prop: 'date', order: 'descending'}">
<el-table-column
prop="expenseCategory"
label="费用类别"
min-width="100"
sortable
:show-overflow-tooltip="true">
</el-table-column>
<el-table-column
prop="orgName"
label="运营公司"
min-width="100"
sortable
:show-overflow-tooltip="true">
</el-table-column>
<el-table-column
prop="contractNumber"
label="合同编号"
min-width="100"
:show-overflow-tooltip="true">
</el-table-column>
<el-table-column
prop="contractName"
min-width="80"
label="合同名称"
:show-overflow-tooltip="true">
</el-table-column>
<el-table-column
prop="payee"
min-width="150"
label="收款单位或个人"
:show-overflow-tooltip="true">
</el-table-column>
<el-table-column
prop="summaryPaymentContent"
label="申请事由"
min-width="120"
:show-overflow-tooltip="true">
</el-table-column>
<el-table-column
prop="appMoney"
label="付款金额"
min-width="130"
:show-overflow-tooltip="true">
</el-table-column>
<el-table-column
prop="fundingPlan"
label="计划月份"
min-width="100"
sortable
:show-overflow-tooltip="true">
</el-table-column>
<el-table-column
prop="payStatus"
label="审批状态"
min-width="80"
:show-overflow-tooltip="true">
</el-table-column>
</el-table>2：js方法
javascript
tableHeJi(val){
const { columns, row } = val;
const sums = [];
columns.forEach((item, index) => {
if (index === 0) {
sums[index] = '总计';
return;
}
else if(index===4){
sums[index] = "合同数量："
return;
}
else if(index===5){
sums[index] = this.heJiObj.contractSum==null
||this.heJiObj.contractSum==""?""
:this.heJiObj.contractSum
return;
}
else if(index===8){
sums[index] = "付款金额合计（元）："
return;
}
else if(index===9){
sums[index] =
this.heJiObj.sum==null||this.heJiObj.sum==""?""
:this.heJiObj.sum
return;
}
});
return sums
},二：自己定义
优点：
可以想表格下面添加多少行都行，
缺点：
列表的序号会一直往下走
