Implementation of fixed header of responsive table

When displaying data, the table header is fixed for better readability.

1. Implementation method:
1. Define 2 tables, one absolute fixed

<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. Copy table 1b4d429308760b6c2d20d6300079ed38e and insert into table 2

var th_new=$("#table1 tr").eq(0).clone();
$("#fixed-table1").append(th_new);

3. The resize() method obtains the b4d429308760b6c2d20d6300079ed38e width of each column in Table 1 in real time

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. If the page is too small, the table scrolls with the header scrolling

$(".table1-wapper").scroll(function(){
	var scroll=-$(this).scrollLeft()
	$(".fixed-table1-wapper").css("left",scroll+"px");
});

2. Pay attention to details:

1. Width adaptive, remove cell gaps:

2. Table line:
Add border directly b6c5a531a458a2e790c1fd6421739d1c and the edges will overlap; add attributes: border-collapse: collapse;

3. td width:
Control the width of the first line da1aa636ba9c30da0dd294d9539dcd40b90dd5946f0946207856a8a37f441edf / adc92a646d90e806e699bafbba898038b90dd5946f0946207856a8a37f441edf

4. Odd and even rows have different colors:
css: #table1 tr:nth-child(2n){background-color:#ccc;} ie7 compatibility issue
jquery: $("#table1 tr:even").css( "background-color","#ccc");
