elementui Table的表头内容过长改为......并提示_elementuitable表头过长

一、效果图

二、代码

我的el-table-column是通过遍历出来的，设置默认width，然后回调render-header

<!-- 测试过滤字段 -->
      <el-table-column 
        v-for="item in clientTranslate" 
        :prop="item.fileterFieldName" 
        :label='item.fileterEnName' 
        :key="item.fileterId"
        v-if="item.isHide"
        width="110px"
        align="center"
        :render-header="tableRenderHeader"  
        show-overflow-tooltip sortable 
      >
        <template slot-scope="scope">
            <span v-if="item.fileterFieldName == 'clientCode'" ><el-link type="primary" @click="opdenDrawer(scope.$index,scope.row,true)">{{ scope.row.clientCode }}</el-link></span>
