            :data="form.tableDataA"
            border
            stripe
            style="width: 100%; margin-top: 20px"
          >
            <el-table-column
              v-for="(category, categoryIndex) in form.tableDataA"
              :key="categoryIndex"
              :label="category.name"
              width="420"
