      <el-table-column prop="deptName" label="事业名称" width="260"></el-table-column>
      <el-table-column prop="releaseType" label="发布类型" width="260">
        <template slot-scope="scope" >
        <dict-tag v-for="a in scope.row.releaseType" :options="dict.type.sys_release_type" :value="a"/>
       </template>
      </el-table-column>
</el-table>

         <el-form-item label="发布类型" prop="releaseType">
           <el-select v-model="form.releaseType" placeholder="请先选择发布类型" multiple  @change="checkedBoxChange">
              <el-option v-for="dict in dict.type.sys_release_type" :key="dict.value" :label="dict.label" :value="dict.value"></el-option> 
            </el-select>
