1 개요[ | ]

HTML 큰 테이블 틀 고정
CSS border-collapse를 separate로 변경하여 컬럼 폭 안맞는 문제를 해결
페이지를 넘는 큰 표에도 대응 (좌우스크롤 가능)
<style>
table { border-collapse: collapse; }
th { background: #cdefff; height: 32px; }
th, td { border: 1px solid silver; padding:5px; }
</style>

<script src="//code.jquery.com/jquery.min.js"></script>
<script>
$(function () {
  $('table.floating-thead').each(function() {
    if( $(this).css('border-collapse') == 'collapse') {
      $(this).css('border-collapse','separate').css('border-spacing',0);
    }
    $(this).prepend( $(this).find('thead:first').clone().hide().css('top',0).css('position','fixed') );
  });
  
  $(window).scroll(function() {
    var scrollTop = $(window).scrollTop(),
      scrollLeft = $(window).scrollLeft();
    $('table.floating-thead').each(function(i) {
      var thead = $(this).find('thead:last'),
        clone = $(this).find('thead:first'),
        top = $(this).offset().top,
        bottom = top + $(this).height() - thead.height();

      if( scrollTop < top || scrollTop > bottom ) {
        clone.hide();
        return true;
      }
      if( clone.is('visible') ) return true;
      clone.find('th').each(function(i) {
        $(this).width( thead.find('th').eq(i).width() );
      });
      clone.css("margin-left", -scrollLeft ).width( thead.width() ).show();
    });
  });
});
</script>
