element中利用tooltip實現文字超出寬度懸浮顯示

實現代碼：

 <el-tooltip :content="data.label" :disabled="data.label.length>22?false:true" placement="top">
       <span class="fieldWidth">{{
           `${data.label} ${
             data.icon === "fieldIcon" ? `(${data.labelType})` : ""
           }`
         }}</span>
</el-tooltip>
