vue2 el-checkbox-group 复选框无法选中

原代码：

<template slot-scope="scope"><el-checkbox v-model="scope.row.bitian">必填</el-checkbox>
</template>if (this.allTemplateList && this.allTemplateList.length > 0) {this.allTemplateList.forEach(template => {template.bitian = false;template.number = '';template.shangchuandatas = [];template.wenjiandaxiao = '';})
},

修改后：在遍历 this.allTemplateList 时，使用 Vue.set 或 this.$set 来确保新添加的属性是响应式的

if (this.allTemplateList && this.allTemplateList.length > 0) {  this.allTemplateList.forEach((template, index) => {  this.$set(this.allTemplateList, index, {  ...template,  bitian: false,  number: '',  shangchuandatas: [],  wenjiandaxiao: '',  });  });  
}
