首先预备一个 SearchCondition ，然后将 searchTarget 设置成 SearchFoundFlags.cellTag 。然后就可以搜索标签了。
通过 sheet.search(searchCondition) 方法来完成搜索。
搜索结果的 foundRowIndex 和 foundColumnIndex 参数说明了第一个匹配的单元格的位置;如果没有找到那么结果都是-1。示例代码如下：
<template>
<div class="sample-tutorial">
<gc-spread-sheets class="sample-spreadsheets" @workbookInitialized="initSpread">
<gc-worksheet />
</gc-spread-sheets>
<div class="options-container">
<div class="option-row">
<label for="txtSearchTag">Search tag equals.</label>
<label>For example enter: B4 tag demo (case sensitive):</label>
<input type="text" id="txtSearchTag" placeholder="tag name" v-model="searchTag" />
</div>
<div class="option-row">
<label for="searchOrder">Search Order:</label>
<select id="searchOrder" v-model="searchOrder">
<option value="0">Column First (ZOrder)</option>
<option value="1">Row First (NOrder)</option>
</select>
<input type="button" id="btnSearchTag" value="Find Tag"
title="Search cell with tag contains specified content and active the cell" @click="handelSearchTag" />
</div>
<div class="option-row">
<label for="txtTag" style=" width: 210px">Selected cell tag:</label>
<input type="text" id="txtTag" v-model="txtTag" />
</div>
</div>
</div>
</template>
