script部分代码

clickAddProblems(rows){
     $this.value.listItem.push({
       key:guid.newGuid(),
       shareholderName:'',
       registeredCapital:null,
       paidinRegisteredCapital:null,
       shareholdingRatio:null
     })
    },
    clickRemoveProblems(row){
       console.log("row:", row);
       $this.value.listItem= $this.value.listItem.filter(x => {
        return x.key != row.key;
      });
    },

表格添加合计行
1. el-table 中添加 show-summary 属性 :summary-method 绑定合计的方法

<el-table border="" :data="value.listItem" show-summary="" :summary-method="getSummaries">

2. 绑定的合计方法

getSummaries(param){
        const { columns, data } = param;
        const sums = [];
         columns.forEach((column, index) => {
         if (index === 0) {
            sums[index] = '合计';
            return;
          } 
          if (index === 0||index === 1||index === 2) {
            sums[index] = '';
            return;
          } 
          const values = data.map(item => Number(item[column.property]));
          console.log(column.property);
          console.log(data);
          if (!values.every(value => isNaN(value))) {
            sums[index] = values.reduce((prev, curr) => {
              console.log(curr);
              const value = Number(curr);
              if (!isNaN(value)) {
                return prev + curr;
              } else {
                return prev;
              }
            }, 0);
            if(index==5){
               sums[index] += ' %';
            }
            else{
             sums[index] += ' 万元';
            }
          } else {
            sums[index] = 'N/A';
          }
        });

        return sums;
    }
