最近项目需要实现可编辑的动态多级表头表格，看了两天的文章，始终没有找到我想要的效果，在了解了render+jsx的基础用法后，自己基于element-ui封装了一个，数据格式参考element-ui table的数据。实现如下：

1.scoresTable

<script>
  import scoresColumn from "./scoresColumn";
  export default {
    components: {
      scoresColumn
    },
    render: function(h) {
      return <div className="table-control">
        <el-table ref="table"
             size="small"
             {...{attrs: {data:this.tableData}}}
             border
        >
          {
            this.tableTitles.map(title => {
              return <scoresColumn on-dataChange={this.dataChange} {...{attrs: {column:title,unitScores: this.unitScores}}}></scoresColumn>
            })
          }

        </el-table>
      </div>;
    },
    props: {
      tableTitles: {
        type: Array,
        default: () => []
      },
      tableData: {
        type: Array,
        default: () => []
      },
      unitScores: {
        type: Object,
        default: () => {}
      }
    },
    methods: {
      dataChange(id) {
        this.$emit('dataChange', id);
      }
    },
  }
</script>
<style>
 .el-table th, .el-table td {
  text-align: center;
 }
</style>

2.scoresColumn

<script>
  export default {
    data() {
     return {
       style: {
         'min-width': "70",
         'resizable': true,
         'show-overflow-tooltip': true
       },
     }
    },
    props: {
     column: {
       type: Object
     },
     unitScores: {
       type: Object,
       default: () => {}
     }
    },
    name: "scoresColumn",
    render: function (h) {
      let scopedSlots = {
        default: (scope) => {
          let col = scope.column.property;
          let value = scope.row[col];
          return <div id={col+scope.$index} >
            <p onClick={this.clickHandle}>{value}</p>
          </div>;
        }
      };
      if (this.column.children === undefined)
        if (this.column.label == '序号' || this.column.label == '姓名') {
          return <el-table-column fixed
            {...{style: this.style, scopedSlots: {
                default: (scope) => {
                  let value = scope.row[scope.column.property];
                  return <p>{value}</p>;
                }
              }}}
            prop={this.column.prop} label={this.column.label}>
          </el-table-column>
        }else {
          return <el-table-column
             {...{style: this.style, scopedSlots: {
                default: (scope) => {
                  let value = scope.row[scope.column.property];
                  if (/\(("text-align: center">
