数据展示时,表头的固定,可以有更好的可读性。
一、实现方式:
1、定义2个表格,一个absolute固定
<div class="table1-wapper"> <table width="100%" cellpadding="0" cellspacing="0" id="table1"> <tr><th><div>序号</div></th><th><div>股票名称</div></th>...</tr> <tr>...</tr> </table> </div> <div class="fixed-table1-wapper"> <table width="100%" cellpadding="0" cellspacing="0" id="fixed-table1"> </table> </div>
2、表1<th>复制,并插入表2
var th_new=$("#table1 tr").eq(0).clone(); $("#fixed-table1").append(th_new);
3、resize()方法,实时获取表1各列<th>宽度
function trResize(){ $("#fixed-table1 th").each(function(){ var num=$(this).index(); var th_width=$("#table1 th").eq(num).width(); $(this).css("width",th_width+"px"); }); }
4、页面过小时,表格滚动带表头滚动
$(".table1-wapper").scroll(function(){ var scroll=-$(this).scrollLeft() $(".fixed-table1-wapper").css("left",scroll+"px"); });
二、注意细节:
1、宽度自适应、去除单元格间隙:
<table width="100%" cellpadding="0" cellspacing="0" ></table>
2、表格线:
直接<td>添加border,会出现边线重合;添加属性:border-collapse: collapse;
3、td宽度:
控制第一行宽度即可<td width="70"></td> / <td width="20%"></td>
4、奇偶行颜色不同:
css: #table1 tr:nth-child(2n){background-color:#ccc;} ie7兼容性问题
jquery: $("#table1 tr:even").css("background-color","#ccc");
