问题：
可水平和垂直滚动的大表格
万俟靖
好吧，这里你是下一篇关于固定页眉和页脚的无聊滚动表的文章。这个主题来自超文本标记语言的刚性结构。源问题是显示非常巨大的表格溢出屏幕宽度作为高度。我的愿望也是将标题固定在表格的顶部，因此将其副本固定在表格的底部。
在大量搜索和测试保证代码后，我发现了下一个深层嵌套问题：-页眉和页脚没有保持表体的单元格间距，而tbody是单独滚动的-tbody行覆盖了页眉-tbody的垂直滚动很难与整个表（包括页眉和页脚）的水平滚动相结合。
我开始写一些黑客来克服它，但它也取决于使用的浏览器。

该解决方案基于创建三个表：页眉表、数据表、页脚表（页眉表的克隆），包含在水平滚动的DIV中。在创建页眉表和数据表后，数据表的自动生成单元格将复制到页眉表的相应单元格。一些缺点是，垂直滚动条隐藏在表格的右侧，但您可以使用鼠标滚轮垂直滚动，或通过水平滚动到完全右侧来显示该条。也许有人在这里展示了一些更好的基于CSS的解决方案，这真的很好，但如果W3C group将定义的正常滚动行为添加到下一个HTML版本中可能会更好。
嗯，这篇文章是作为html滚动表的功能示例编写的，固定的页眉和页脚总是可见的。既不少，也不多，装饰也不好看。基本任务是尽可能简单地编写。由于该表是更复杂的html页面的一部分，包含公式和其他表，因此排除了全局CSS。在过去30年中，W3C对HTML功能进行了大量开发，我想到了以下内容：
<table style="overflow:scroll; overflow-y:hidden; display:@in_parent_element_only">
<thead style="'header cells corresponding with table cells'">
<row><!--single row header --></row></thead>
<tbody style="overflow:scroll; overflow-x:hidden; 'full_view_table'">
<row><!--lot of rows --></row></tbody>
<tfoot ><row><!--copy of header --></row></tfoot>
</table>
不幸的是，这应该是一个太简单的方式-实际上我测试了很多风格组合，但要么THEAD和TBODY细胞没有关联（为什么？），或者THEAD、TBODY、TFOOT行相互重叠或置换，反之亦然。
我知道，一个非常好的结果可以通过繁重的计算、定位和造型来寻找，但我坚持简单性和功能性，更喜欢信息而不是装饰品。
如果有人知道内联style="..."的什么组合可以保证无论浏览器类型如何都能获得良好的结果，请尝试在这里写一段注释良好的代码。不仅对我来说，而且对共存来说，就像我在这里展示我的原始方式一样。

这里有一个最小的解决方案，以防有人想要一个快速的答案。
你只需要一个滚动div包装器，在th元素上，位置：sticky 到顶部和背景。就是这样
th {
background: aquamarine;
position: sticky;
top: 0px;
}
.table-wrapper {
border: solid 1px black;
height: 200px;
max-width: 200px;
overflow: scroll;
} <div class="table-wrapper">
<table>
<thead>
<tr>
<th>Header1</th>
<th>Header2</th>
<th>Some other Header</th>
<th>Header3</th>
</tr>
</thead>

我在stackoverflow中深入搜索了类似问题的答案，并使用一部分CSS（甚至没有完全理解）重写了我的解决方案。
数据是通过PHP对psql数据库的请求生成的，因此它可以返回需要滚动的非常大的表。
CSS部分是从各种来源编译的，并仔细查阅CSS教程和手册。但主要的灵感来自“http://stackoverflow.com/users/9557859“的答案”http://stackoverflow.com/questions/47723996“问题（都在这个网站上）。

我正在使用GridView创建一个组件来创建像Excel这样的表。在这里，我最初创建了一个2x2网格，稍后当用户单击按钮时，会添加额外的行和列。 这是我添加新专栏的做法：- 这可以正常工作并添加额外的列。问题是当添加列时，以前的列会收缩以适应新列，从而使每次添加新列时列看起来更小。我想一次只在屏幕上显示2列，然后让用户水平向前滚动以查看更多列。现在网格只能垂直滚动。同样，我希望在添加新行时发生这种

问题内容： 如标题中所述，我一直在尝试通过水平滚动设置某种垂直流布局。布局中的组件将是JLabels。让我画一幅画： 同一窗口，垂直扩展 因此，标签将填充可用的垂直空间，然后创建一个新列。一旦可用的水平空间用尽，就会出现一个 水平 滚动条。 垂直滚动条通常不应出现；但是，如果窗口的垂直高度异常小，最好有一个垂直滚动条。 任何帮助是极大的赞赏。我是Java的新手，所以任何其他解释都将是很棒的。谢谢！

我一直在努力解决HTML/CSS粘滞头+滚动条的问题。我们正在创建一个程序，一旦containersize达到某个点（取决于用户的分辨率），就需要滚动条显示出来。 我在表中的第二列上强制设置一个min-width,因此表在某个点停止递减,并强制容器保持在某个宽度。容器上的溢出显示水平滚动条。一切正常。一旦我为垂直滚动添加了第二个滚动条，事情就会变得一团糟。有人有解决这个问题的办法吗？我想在.tab

A有一个图像，并希望能够在固定大小的可滚动区域中放大/缩小它。这很容易，但如果图像小于可滚动区域，则应该在垂直和水平方向上居中。我找不到一个解决办法，如何把它在中间垂直对齐。流行的解决方案，如垂直对齐一个div内的图像与响应的高度，或如何垂直居中一个div为所有浏览器？不工作，因为可滚动区域。 http://jsfidle.net/smvyadnv/9/ HTML CSS

我在水平滚动视图中实现了一个表格布局，这也是垂直滚动视图的一部分。它是这样工作的；当垂直或水平滚动时，它会为每种滚动类型显式滚动。意思是当垂直滚动时，水平滚动根本不会发生，比如说，如果手指对角移动，就不会发生垂直或水平滚动。要水平滚动，必须再次触摸它，并且它只在水平方向滚动，如果手指对角移动，就不会发生垂直或水平滚动。[这里也是如此]。 一次手指触摸似乎只处理一次回调。我也需要对角线滚动，应该同时

我想制作一个类似视图的电子表格来显示一些数据。到目前为止，这是我所拥有的，但我一次只能滚动一种方式。我希望能够同时水平和垂直滚动。 现在我有一个水平滚动视图内的回收器视图。 这是我的回收器查看行布局。 这是我在Java中设置我的recyclerView的地方。 任何帮助都将不胜感激。谢谢！
