1.写一个简单的table表格框架
<table> <thead class="my-table"> <tr> <th>姓名</th> <th>年龄</th> <th>性别</th> </tr> </thead> <tbody> <tr v-for="(item, index) in tableData" :key="index"> <td>{{ item.name }}</td> <td>{{ item.age }}</td> <td>{{ item.address }}</td> </tr> </tbody> </table>table里的数据在data里返回，以下是实例数据
tableData: [ { name: "张三", age: 30, address: "北京市朝阳区" }, { name: "李四", age: 28, address: "上海市浦东新区" }, { name: "王五", age: 32, address: "广州市天河区" }, { name: "赵六", age: 25, address: "深圳市福田区" }, { name: "孙七", age: 27, address: "成都市武侯区" }, ],这样我们就拥有了一个没有样式的基础表格
2.为了使表格更好看，我实现了如下几步：
- 固定表头，滚动时保留表格上面的标题
将th的 position设置为sticky，固定首行，也就是top=0，为其设置为一个区分的颜色
th { background-color: #3c7ca7; font-weight: bold; position: sticky; top: 0; background-color: rgb(110, 138, 163); }- 将表格间的分割线去除
<table cellspacing="0" > <--...table内容--> </table>- 修改表格背景颜色，字体等样式
为了好看点还设置了隔行的颜色区分也就是 tr:nth-child(even)
th, td { padding: 20px; text-align: center; font-family: '微软雅黑',"times","courier","arial"; font-weight:"medium"; //border: 1px solid #ccc; font-size: 20px; color: #ffffff; } th { background-color: #3c7ca7; font-weight: bold; position: sticky; top: 0; background-color: rgb(110, 138, 163); } tr:nth-child(even) { background-color: #3c7ca7; }- 自动滚动效果
首先为了滚动效果的顺利实现，给table类增加一个外框类table-container
增加滑动框并隐藏
.table-container { overflow-y: scroll; -webkit-overflow-scrolling: touch; } .table-container::-webkit-scrollbar { display: none; }然后利用timer定时器和scrollTop 属性设置滚动效果，
mounted() { this.timerId = setInterval(() => { const tableContainer = this.$refs.tableContainer; const rowHeight = tableContainer.querySelector('tbody tr').offsetHeight; tableContainer.scrollTop += rowHeight; if (tableContainer.scrollTop == lasttop) { tableContainer.scrollTop = 0; }else{ lasttop=tableContainer.scrollTop } }, 2000); this.init(); }, beforeDestroy() { // 在组件销毁前清除 setInterval clearInterval(this.timerId);},
由于上面的滚动效果不好，看起来很卡顿，下面优化了滚动效果，加入缓动
mounted() { this.timerId = setInterval(() => { const tableContainer = this.$refs.tableContainer; const rowHeight = tableContainer.querySelector('tbody tr').offsetHeight; tableContainer.scrollTop += rowHeight/30; if (tableContainer.scrollTop == lasttop) { tableContainer.scrollTop = 0; }else{ lasttop=tableContainer.scrollTop } }, 30); this.init(); // this.tableroll(); },- 最后实现效果
3.全部代码
<div class="table-container" ref="tableContainer"> <table cellspacing="0" > <thead class="my-table"> <tr> <th>姓名</th> <th>年龄</th> <th>性别</th> </tr> </thead> <tbody> <tr v-for="(item, index) in tableData" :key="index"> <td>{{ item.name }}</td> <td>{{ item.age }}</td> <td>{{ item.address }}</td> </tr> </tbody> </table> </div> export default { data() { tableData: [ { name: "张三", age: 30, address: "北京市朝阳区" }, { name: "李四", age: 28, address: "上海市浦东新区" }, { name: "王五", age: 32, address: "广州市天河区.dfasfaweorfaiadsfasd" }, { name: "赵六", age: 25, address: "深圳市福田区" }, { name: "孙七", age: 27, address: "成都市武侯区" }, ], }, .table-container::-webkit-scrollbar { display: none; } .table-container { position: absolute; left: 80%; top:70%; height: 300px; overflow-y: scroll; -webkit-overflow-scrolling: touch; background-color:rgba(18, 76, 117, 0.7); .my-table { } th, td { padding: 20px; text-align: center; font-family: '微软雅黑',"times","courier","arial"; font-weight:"medium"; //border: 1px solid #ccc; font-size: 20px; color: #ffffff; } th { background-color: #3c7ca7; font-weight: bold; position: sticky; top: 0; background-color: rgb(110, 138, 163); } tr:nth-child(even) { background-color: #3c7ca7; } }
