javascript - 带有固定标题的嵌入式表格垂直滚动

Question

我有一个嵌入另一个div的表格，当然尺寸比外面的div大。我目前正在使用 ScrollToFixed在滚动时将标题固定在顶部，并在表格内容超出视口(viewport)时再次保留它。这行得通，但真正丑陋的是，虽然标题行是固定的，但它大于内容，因此它在左/右溢出。

请参阅the Fiddle它确实按描述工作的地方。我能想象的是以某种方式设置表格的固定高度和宽度，并且它应该可以垂直和水平滚动，因为有溢出并且第一行应该固定在滚动时。

$(document).ready(function() {
  var scrollLeft = 0;
  var leftRoundingRect = $('.table-body')[0].getBoundingClientRect().left;

  $('.sticky').scrollToFixed({
    limit: $('.user.last').offset().top,
    removeOffsets: true,
    zIndex: 0,
    unfixed: function() {
      $(this).offset({
        left: leftRoundingRect - scrollLeft
      });
    }
  });

  $(".table-body").scroll(function() {
    scrollLeft = this.scrollLeft;
    $(".user.sticky").offset({
      left: leftRoundingRect - scrollLeft
    });
  });
});

.tab {
  padding: 20px;
  border: 1px solid lightgray;
}

.inner-content {
  overflow: hidden;
  padding: 0 10px 0 10px;
}

.table-body {
  overflow: auto;
}

.users {
  white-space: nowrap;
  font-size: 0;
}

.user {
  font-size: 0;
  border-bottom: 1px solid #d3d3d3;
  border-left: 1px solid #d3d3d3;
  color: #555;
  width: 750px;
}

.user.odd {
  background: #f4f5f7;
}

.sticky {
  background: grey;
}

.bold {
  color: #fff;
  font-weight: 600;
}

下面的代码确实像我描述的那样工作。

$(document).ready(function() {
  var scrollLeft = 0;
  var leftRoundingRect = $('.table-body')[0].getBoundingClientRect().left;

  $(".table-body").scroll(function() {
    scrollLeft = this.scrollLeft;
    $(".user.sticky").offset({
      left: leftRoundingRect - scrollLeft
    });
  });
  
  $(".user").width($(".table-body").get(0).scrollWidth - 1);
  
});

.tab {
  padding: 20px;
  border: 1px solid lightgray;
  width:220px;
}
.inner-content {
  padding: 0 10px 0 10px;
  width:200px;
}
.header {
  overflow: hidden;
}
.table-body {
  overflow: auto;
  height: 100px;
}
.users {
  white-space: nowrap;
  font-size: 0;
}
.user {
  font-size: 0;
  border-bottom: 1px solid #d3d3d3;
  border-left: 1px solid #d3d3d3;
  color: #555;
  width: 750px;
}
.user.odd {
  background: #f4f5f7;
}
.sticky {
  background: grey;
}
.bold {
  color: #fff;
  font-weight: 600;
}
.company,
.firstName,
.lastName,
.roles {
  font-size: 18px;
  border-right: 1px solid lightgray;
  display: inline-block;
  width: 150px;
  padding: 10px;
  overflow: scroll;
  white-space: nowrap;
}
