问题记录：

记录在动态表头的时候，点击单元无法添加/编辑的问题，DOM结构中只有span没有el-input框

<el-tab-pane label="配置各单位总部业务比例" name="second">
        <template>
          <el-table :data="tableData2" style="100%;" border>
            <el-table-column type="index" width="50" label="序号"></el-table-column>
            <el-table-column prop="deptTypeTrans" label="类型"></el-table-column>
            <el-table-column prop="deptName" label="部门"></el-table-column>
            <el-table-column v-for="item in tableData2" :key="item.id" :label="item.companyName" :prop="item.prop">
              <template slot-scope="scope" >
                <span class="sine" @click="dataClick(scope.row, scope.row.rate)" v-if="!scope.row.rate.edit">{{scope.row.rate.label}}</span>
                <el-input 
                  size="mini" 
                  oninput="value=value.replace(/[^d.]/g,'')" 
                  v-focus 
                  v-else 
                  v-model="scope.row.rate.label" 
                  @blur="loseFcous(scope.row, scope.row.rate)">
                </el-input>
              </template>
            </el-table-column>
          </el-table>
          <div class="dialog-footer">
            <el-button size="small" type="primary" @click="handleSave2()">保存</el-button>
            <el-button size="small" type="info" @click="handleCancel2()">取消</el-button>
          </div>
        </template>
      </el-tab-pane>

methods: {
   loseFcous(row, name) {
        console.log(row, name);
        name.edit = false;
     },
    dataClick(row, name) {
        console.log(row, 'name');
        name.edit = true;
    },
   //获取各单位总部业务比例
	getBusinProportion() {
		let params = {
      queryFields:JSON.stringify({
        id: '',
        annual: this.searchParams.annual,					
        checkDeptId: '',					
        companyId: '',	
        rate: '',		
      })
		}
		this.$axios({
      method: 'get',
      url: this.getBusinExList,
      params: params
		}).then((res) => {
      console.log(res, '各单位总部业务比例数据')
      res.data.results.forEach(item => {
        item.rate = {
          label: item.rate || 10,
          edit: false
        }
      })
      this.tableData2 = res.data.results;
      console.log(this.tableData2, 'tableData2');
		})
	}    
}

原因：

1、更改视图$set用错了

    loseFcous2(row, name) {
        console.log(row, name.edit);
        this.$set(name, 'edit', false); //源数据、key、value
     },
    dataClick2(row, name) {
        console.log(row, name.edit);
        this.$set(name, 'edit', true);
    },

 2、自定义指令 v-focus影响的

因为v-focus是焦点存在或者离开的时候隐藏的，所以值是true的时候，指令又处理一次，焦点没存在当前input上。（点击按钮，input显示 但是input没焦点）
