我有一个表格，其标题与表格底部对齐。该表有很多行。问题是只有在我将表格一直滚动到底部时才能看到标题。无论行数和是否需要滚动条，如何使其可见？
我需要一个新的div或类似的东西??

像这样的东西
$(function() {
$('#id').bind('scroll', function() {
$('.caption').css('display','block');
})
});
<div class="caption" style="position:fixed;bottom:0px;display:none;">
被修改
<script>
$(document).ready(function(){
$('#ids').bind('scroll', function() {
if($(this).scrollTop()){
$('.caption').css('display','block');
} else {
$('.caption').css('display','none');
}
})
});
</script>
<div id="ids" style="height:100px;width:100px;overflow-y:scroll;border:1px solid #f00;">
<table style="table-layout: fixed">

只需添加这样的东西（当然你可以随意设计）
caption{position:fixed; bottom:0; background:#fff;}
