需求

一個表單中存在子表

列表返回格式

在這里插入圖片描述

el-table中在嵌套一個el-table，這樣數(shù)據(jù)格式就沒問題了，主要就是樣式

將共同的列放到一列中，通過渲染自定義表頭render-header，將表頭按照合適的寬度渲染出來

 <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

         label="申請?zhí)鞌?shù)"
         width="120px"
       ></el-table-column>
       <el-table-column

       ></el-table-column>
       <el-table-column
         prop="actualDay"
         align="center"
         label="實際出差天數(shù)"
         width="120px"
       ></el-table-column>
       <el-table-column
         prop="subsidyDay"
         align="center"
         label="差補天數(shù)"
         width="120px"
       ></el-table-column>

       ></el-table-column>
     </el-table>
   </template>
 </el-table-column>

根據(jù)數(shù)據(jù)渲染表頭

      childColumn: [
        {
          label: "起始日期",
          width: "120px",
        },
        {
          label: "結(jié)束日期",
          width: "120px",
        },
        {
          label: "申請?zhí)鞌?shù)",
          width: "120px",
        },
        {
          label: "目的地",
          width: "120px",
        },
        {
          label: "交通方式",
          width: "120px",
        },
        {
          label: "出差事由",
          width: "120px",
        },
        {
          label: "返程日期",
          width: "120px",
        },
        {
          label: "實際出差天數(shù)",
          width: "120px",
        },
        {
          label: "差補天數(shù)",
          width: "120px",
        },
        {
          label: "備注",
          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
      );
    },

調(diào)樣式，慢慢調(diào)到合適就行

.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;
  }
}
