vue3 element plus table 使用固定列，滑动滚动会错位、固定列层级异常、滑动后固定列的内容看不到了

源码

<el-table
        class="custom-table"
        row-key="merchant_category_id"
        v-loading="loading"

table-layout="fixed"
        :data="tableData"
tooltip-effect="light"

        empty-text="暂无数据"
        @select="selectTable"
          @select-all="selectAllTable"
          :cell-style="{ textAlign: 'center' }"
	        :header-cell-style="{textAlign: 'center'}"
          ref="multipleTableRef"

        <el-table-column fixed label="商家名称"class-name="zindex2" property="mer_name" min-width="240">
          <!-- <template #default="scope">{{ scope.row.category_name }}</template> -->
        </el-table-column>
        <el-table-column property="category_name" label="分类名称" width="120" />

            <template #default="scope">
              <el-tag  :type="scope.row.mer_state==1?'success':'danger'">{{scope.row.mer_state==1?"开启":"关闭"}}</el-tag>

            </template>

          <el-table-column property="margin" label="保证金" width="200" />
        <el-table-column property="address" label="操作" fixed="right" width="280">
          <template #default="scope">
            <div class="cz_text">
               <span class="bj" >登录店铺</span>
              <span class="bj" @click="updataPwd(scope.row)">修改密码</span>
              <span class="bj" @click="updataPwd(scope.row)">营业执照</span>
               <span class="bj" @click="editDetail(scope.row)">编辑</span>
              <!-- <span class="look">查看</span> -->
            </div>
          </template>
        </el-table-column>
      </el-table>

效果

• 滚动条滑动后分类名称会盖住商家名称

说明

1、 table-layout=“auto”
2、 el-table-column 要设置列宽 或者就设置min-width就不会出现这个问题了
