防止滚动表中的单个列
本文关键字：单个列 滚动 | 更新日期: 2023-09-27 18:03:46
好吧，向导们，有人知道怎么做…
我有一个非常复杂的自定义控件，它呈现x人数(可能是1也可能是100)的可用性信息。日历呈现控件属性中指定的任何给定日期范围。
这意味着控件有可能非常长，并且所有这些数据都呈现为html表。
每个人的名字都出现在第一列，我希望修复这一列，并让表的其余部分水平滚动，这样用户可以浏览完整的日期范围，但仍然可以看到人名。
那么我如何修复表中第一列的位置，看起来像下面的代码…
<table>
<tr><td></td><td colspan='31'>Jan</td><td colspan='28'>feb</td>...</tr>
<tr><td></td><td>1</td><td>2</td><td>3</td> ...<tr/>
<tr><td>Person 1</td><td></td><td></td><td>Busy</td> ...<tr/>
<tr><td>Person 2</td><td></td><td>Busy</td><td>Busy</td> ...<tr/>
</table>
如果它在任何方面都有帮助，这是一个c#应用程序(asp.net)，如果需要，我愿意使用javascript。
谢谢大家
这是Markku utula的一个解决方案，它使用CSS和HTML的组合(如下)。让我惊讶的是，即使在IE6上也能以合理的性能工作。V.令人印象深刻的工作。由于某些原因，Chrome, Opera和Firefox的滚动条最终会在冻结的列/行下面，但希望这些条足够大，这不会是一个问题…

好的，所以根据上面的表格，我已经我不得不假设固定列将有一个固定的宽度，但我设法做到了这一点…
<div style="position:relative;">
<div style="width:100%; overflow:scroll; height:400px;">
<table style="margin-left:100px;">
<tr><td style="position:absolute;"></td><td colspan='31'>Jan</td><td colspan='28'>feb</td>...</tr>
<tr><td style="position:absolute;"></td><td>1</td><td>2</td><td>3</td> ...<tr/>
<tr><td style="position:absolute;">Person 1</td><td></td><td></td><td>Busy</td> ...<tr/>
<tr><td style="position:absolute;">Person 2</td><td></td><td>Busy</td><td>Busy</td> ...<tr/>
</table>
</div>
</div>
这将导致标记的单元格占据左侧的绝对位置，并且表格仍然是可滚动的…需要做一点工作来清理它，使它看起来很漂亮，但基本上我的代码在提取出来时看起来像这样…
<style type="text/css">
.Calendar { max-height:400px; border-collapse:collapse; table-layout:fixed; margin-left:105px; }
.Calendar .Resources { width:100px; position:absolute; left:0px; background:white; }
.Calendar tr { vertical-align:top; }
.Calendar td { border:solid 1px black; vertical-align:top; padding:2px; border:solid 1px #EFEFEF; }
.Calendar .day { background:#FFFBD6; border:solid 1px #FEEFB3; }
.Calendar .dayWithEvent { background:white; border:solid 1px #FEEFB3; border-top:solid 1px blue; }
</style>
<div style="position:relative;">
<div style="width:100%; overflow:scroll; height:400px;">
<table class="Calendar">
<asp:Repeater ID="ui_calMonths" runat="server" onitemdatabound="ui_calMonths_ItemDataBound">
<HeaderTemplate>
<tr><td class="Resources" style="background:white; border:none;"> </td>
</HeaderTemplate>
<ItemTemplate>
<td colspan='<%# ((Month)Container.DataItem).Days.Length %>'><%# Eval("Name") %></td>
</ItemTemplate>
<FooterTemplate>
</tr>
<tr><td class="Resources" style="background:white; border:none;"> </td>
<asp:Repeater ID="ui_calDays" runat="server">
<ItemTemplate>
<td><%# ((DateTime)Container.DataItem).ToString("dd") %></td>
</ItemTemplate>
</asp:Repeater>
</tr>
</FooterTemplate>
</asp:Repeater>
<asp:Repeater ID="ui_grdResources" runat="server">
<HeaderTemplate><tr></HeaderTemplate>
<ItemTemplate>
<td class="Resources"><%# Eval("Text") %></td>
<%# ResourceEvents(((RowContext)Container.DataItem)) %>
</ItemTemplate>
<FooterTemplate></tr></FooterTemplate>
</asp:Repeater>
</table>
</div>
</div>
基本上，代码后面计算出每行中要呈现多少单元格(重复器在此工作中是基础的，但结果本质上是一个格式良好的表，其中包含第一行给定日期范围的月份名称，第二个月的天数，第三个固定列包含名称和动态填充从我的内部API日历项…非常酷!!
