Javascript 固定标题和可滚动正文
我在表中有15列。我想滚动水平和垂直和标题应该是固定的,当我滚动垂直。我试过各种各样的例子,但都不走运。我看到的所有标题列都没有与数据对齐。列宽不是固定的,因为列数根据用户选择而变化Javascript 固定标题和可滚动正文,javascript,html,css,Javascript,Html,Css,我在表中有15列。我想滚动水平和垂直和标题应该是固定的,当我滚动垂直。我试过各种各样的例子,但都不走运。我看到的所有标题列都没有与数据对齐。列宽不是固定的,因为列数根据用户选择而变化 请引导我找到正确的示例。使用css很容易实现。这一切归结于以下几点: table { overflow-x:scroll; } tbody { max-height: /*your desired max height*/ overflow-y:scroll; display:bl

为IE9更新
您应该使用一些第三方表格,如您所能做的是使用一些视觉技巧来实现这一点, 使用两个div标记
<div class="Headers">
<table class="NewHeader">
<tr>
</tr>
</table>
</div>
<div class="Table">
<table class="MyTable">
<tr>
<th>
</th>
...
</tr>
<tr>
<td>
</td>
...
</tr>
</div>
现在唯一要做的就是用溢出设置div“Table”的样式,所以现在如果滚动第二个表,标题将保持不变,我使用jquery简化可读性,但可以用JavaScript完成,方法相同
我发现一个系统
- 与Internet Explorer 9+Chrome+Firefox(Windows)和Safari(Mac)兼容
- 不使用javascript
- 仅使用une div和一个表
- 固定页眉和页脚(IE除外),具有可滚动的正文。标题和正文具有相同的列宽
下面是一个使用TableRegulator和TableData类的纯javascript解决方案:
.hdrDiv
{
宽度:100%;
溢出x:隐藏;
}
tblDiv先生
{
溢出y:自动;
溢出x:隐藏;
保证金:0;
填充:0;
高度:500px;
}
.hdr
{
宽度:100%;
}
.hdr td、.tbl td
{
左侧填充:8px;
右边填充:8px;
垂直对齐:中间对齐;
边框样式:实心;
边框宽度:1px;
边框颜色:rgb(163163);
文本对齐:左对齐;
游标:默认值;
保证金:0;
}
.hdr td
{
字体:粗体12px塔荷马;
垫面:4px;
垫底:4px;
}
.hdr td.col1
{
宽度:20%;
}
.hdr td.col2
{
宽度:20%;
}
.hdr td.col3
{
宽度:25%;
}
.hdr td.col4
{
宽度:35%;
}
.hdr,.tbl
{
表布局:固定;
最小宽度:400px;
}
.tbl td
{
字体:12px塔荷马;
}
var g_调节器=零;
var g_initRowCount=4;
函数getScrollbarWidth()
{
var outer=document.createElement(“div”);
outer.style.visibility=“hidden”;
outer.style.width=“100px”;
文件.正文.附件(外部);
var widthNoScroll=外部偏移网络宽度;
outer.style.overflow=“滚动”;
var internal=document.createElement(“div”);
inner.style.width=“100%”;
外部。子对象(内部);
var widthWithScroll=内部偏移网络宽度;
outer.parentNode.removeChild(outer);
返回宽度NoScroll-宽度widthWithScroll;
}
函数ExtractInt(值)
{
var regExp=/([a-zA-Z])/g;
value=value.replace(regExp,“”);
返回值(value.length==0)?0:parseInt(值);
}
函数TableData(hdrID、tableID)
{
this.m_hdrID=hdrID;
this.m_tableID=tableID;
该宽度为0.m_pbWidth;
var header=document.getElementById(this.m_hdrID);
var table=document.getElementById(this.m_tableID);
this.m_hasb=table?(table.parentNode.scrollHeight>table.parentNode.clientHeight):false;
var hdrRow=(header!=null&&header.rows.length>0)?header.rows[0]:null;
var clsName=!hdrRow?“:(hdrRow.className.length>0)?hdrRow.className:(header.className.length>0)?header.className+“td”:”;
var元素=[];
push({prop:'padding left',值:''});
push({prop:'padding right',值:''});
push({prop:'border width',值:''});
this.getcss值('.'+clsName,元素);
对于(变量i=0;i=0)
{
对于(变量k=0;k 0)
元素[k]。值=v;
}
}
}
}
}
TableData.prototype.Adjust=
函数(sbWidth)
{
var header=document.getElementById(this.m_hdrID);
var table=document.getElementById(this.m_tableID);
var hdrRow=(header!=null&&header.rows.length>0)?header.rows[0]:null;
如果(!hdrRow | |!表格)
返回;
var hasSB=table.parentNode.scrollHeight>table.parentNode.clientHeight;
header.style.width=hasb?“计算(100%-”+sbWidth.toString()+“px)”:“100%”;
var colCount=hdrRow.cells.length;
对于(VARI=0;I0)?header.rows[0]:null;
如果(!hdrRow | |!表格)
返回;
var colCount=hdrRow.cells.length;
var rowNum=table.rows.length+1;
var r=表.插入行(-1);
对于(var i=0;i我为这个问题创建了一个纯CSS解决方案,它可能比公认的答案对某些人更有效(我似乎一点也不起作用)。与我见过的大多数不需要固定宽度的滚动正文表格不同,我的表格有一个由其内容决定的最小宽度。如果可能,它将包装文本以避免容器溢出(遗憾的是,标题中不允许软包装),但一旦包装机会用完,就不会再窄了。这迫使父元素(通常是body标记)处理水平滚动,从而保持标题和列的同步
