修复方案

1. 确认PrimeFlex依赖加载

PrimeNG的布局类依赖PrimeFlex库，需确保项目已集成：

安装：npm install primeflex

在angular.json的styles数组中引入样式：

"styles": [
  "node_modules/primeflex/primeflex.css",
  // 其他项目样式文件
]

2. 修正网格布局列类名

将网格项的col-12 md:col-4替换为PrimeNG标准前缀的类p-col-12 p-md-4，确保与DataView的布局容器兼容：

<ng-template let-product pTemplate="gridItem">
    <div class="p-col-12 p-md-4">
        <div class="product-grid-item card">
            <!-- 原有内容不变 -->
        </div>
    </div>
</ng-template>

3. 修复搜索栏元素对齐

给头部容器添加垂直居中类md:align-items-center，确保布局元素对齐：

<ng-template pTemplate="header">
    <div class="flex flex-column md:flex-row md:justify-content-between md:align-items-center">
        <!-- 原有内容不变 -->
    </div>
</ng-template>

4. 限制卡片宽度避免撑满容器

在CSS中给网格卡片添加最大宽度和自动外边距，控制卡片尺寸：

:host ::ng-deep .product-grid-item {
    max-width: 320px;
    margin: 0.5em auto;
    border: 1px solid #dee2e6;
}
