实现冻结解冻功能

核心：给多选框绑定 disabled 属性，属性为数组，当在数组中找到则为冻结。

 <div class="fieldContainer">
   <div class="left">
     <el-checkbox
       :indeterminate="isIndeterminate"
       v-model="checkAll"
       @change="handleCheckAllChange"
       >全选</el-checkbox
     >
     <el-checkbox-group
       v-model="checkedTexts"
       @change="handleCheckedTextsChange"
     >
       <el-checkbox
         v-for="item in texts"
         :label="item"
         :key="item"
         :disabled="
           disableArray.length > 0 && disableArray.indexOf(item) != -1
         "
         >{{ item }}</el-checkbox
       >
     </el-checkbox-group>
   </div>
