最近專案需要實現可編輯的動態多級表頭表格，看了兩天的文章，始終沒有找到我想要的效果，在瞭解了render+jsx的基礎用法後，自己基於element-ui封裝了一個，資料格式參考element-ui table的資料。實現如下：

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,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 == '序號' || 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 (/\((?=\d)|(^總計$)/g.test(this.column.label)) {
                    let col = scope.column.property;
                    return <div id={col+scope.$index} >
                      <p onClick={this.clickHandle}>{value}</p>
                     </div>;
                  }else return <p>{value}</p>;
                }
               }}}
             prop={this.column.prop} label={this.column.label}>
          </el-table-column>
        }
      let buildTitles = (childList) => {
        let children = [];
        childList.map(child => {
          if (child.children != undefined && child.children.length > 0) {
            children.push(<el-table-column {...{style: this.style}} label={child.label}>
              {buildTitles(child.children)}
            </el-table-column>)
          } else {
            children.push(
              <el-table-column {...{style: this.style,scopedSlots: scopedSlots}}
                       label={child.label} prop={child.prop}>
              </el-table-column>)
          }
        });
        return children;
      };
      return <el-table-column
        {...{style: this.style}}
        label={this.column.label}
        prop={this.column.prop}>
        {buildTitles(this.column.children)}
      </el-table-column>;
    },methods: {
      blurHandler(e) {
        let parent = e.target.parentNode;
        let child = parent.firstElementChild;
        let p = document.createElement('p');
        let value = child.value.match(/^\d*(\.{1}\d+)?/)[0];
        if (value == '' || value == null) {
          value = 0;
        }
        p.innerHTML = value;
        p.addEventListener('click',this.clickHandle,false);
        child.replaceWith(p);
        this.$emit('dataChange',parent.id);
      },clickHandle(e) {
        let parent = e.target.parentNode;
        let child = parent.firstElementChild;
        let input = document.createElement('input');
        input.style.lineHeight = '23px';
        input.style.textAlign = 'center';
        input.style.fontSize = '12px';
        input.style.height = '23px'
        input.style.width = '100%';
        input.value = child.innerHTML;
        input.addEventListener('blur',this.blurHandler,true);
        input.addEventListener('keyup',this.keyUpHandler,false);
        child.replaceWith(input);
        input.focus();
      },keyUpHandler(e) {
        let input = e.target;
        let parent = input.parentNode;
        let property = parent.id.replace(/\d/g,'');
        let value = input.value.replace(/[^\d\.]/g,'');
        if (Math.min(this.unitScores[property],value) != value) {
          value = this.unitScores[property];
        }
        input.value = value;
      }
    }
  }
</script>
<style scoped>
</style>
