elementui组件table表，同时合并列和行的问题

 

项目需要实现每三行合并两行，然后每三行合并三列，下图这种效果：

代码：

<el-table :data="tableData" :span-method="arraySpanMethod" border style="width: 100%"> <el-table-column prop="id" label="ID" width="180">
      </el-table-column>
      <el-table-column prop="name" label="姓名">
      </el-table-column>
      <el-table-column prop="amount1" sortable label="数值 1">
      </el-table-column>
      <el-table-column prop="amount2" sortable label="数值 2">
      </el-table-column>
      <el-table-column prop="amount3" sortable label="数值 3">
      </el-table-column>
    </el-table>

vue部分：

var Main = { data() { return { tableData: [{ id: '12987122', name: '王小虎', amount1: '234', amount2: '3.2', amount3: 10 }, { id: '12987123', name: '王小虎', amount1: '165', amount2: '4.43', amount3: 12 }, { id: '12987124', name: '王小虎', amount1: '324', amount2: '1.9', amount3: 9 }, { id: '12987125', name: '王小虎', amount1: '621', amount2: '2.2', amount3: 17 }, { id: '12987126', name: '王小虎', amount1: '539', amount2: '4.1', amount3: 15 }, { id: '12987126', name: '王小虎', amount1: '666', amount2: '4.1', amount3: 15 }, { id: '12987126', name: '王小虎', amount1: '777', amount2: '4.1', amount3: 15 }, { id: '12987126', name: '王小虎', amount1: '888', amount2: '4.1', amount3: 15 }, { id: '12987126', name: '王小虎', amount1: '999', amount2: '4.1', amount3: 15 }] }; }, methods: { arraySpanMethod({ row, column, rowIndex, columnIndex }) { if(columnIndex === 0) {
　　　　　　//每三行，合并两行 if ((rowIndex+1) % 3 === 1) { return { rowspan: 2, colspan: 1 }; }else if ((rowIndex+1) % 3 === 0 ) { //每三行合并三列  return [1, 3]; } } } } }; var Ctor = Vue.extend(Main) new Ctor().$mount('#app')
