vue+element 字典表 类型转换(解决复现的时候没有数据)

    <el-table-column
                  prop="leftKey"
                  align="center"
                  width="210"
                  label="包装物"
                >
                  <template slot-scope="scope">
                    <!-- <el-input
                    v-model.trim="scope.row.packagings"
                    :disabled="disabled"
                    :maxlength="10"
                    placeholder="包装物"
                  ></el-input> -->

                    <!-- <span>{
   
   {
                      transDict('PACK_TYPE', scope.row.packagings)

                    <div v-if="scope.row.packagings">
                      {
