制作第一行的固定标题

Question

演示

<div id="divScroll" style="overflow-x: hidden">
    <table id="tableAppointment" bgcolor="#fcfcfc" border="1" cellspacing="1" width="100%">

            <tr>
                <td class="csstextheader" width="70px"></td>
                <td class="csstextheader" width="70px">
                    <b>Time Slot&nbsp;</b>
                </td>
                <td><b>Room 7</b></td>
                <td><b>Room 8</b></td>
                <td><b>Room 9</b></td>
                <td><b>Room 10</b></td>
            </tr>



            <tr class="csstablelisttd">
                <td width="70px">08:00AM</td>
                <td>00</td>
                <td class="csstdred">John</td>
                <td>&nbsp;</td>
                <td>&nbsp;</td>
                <td>&nbsp;</td>                                     
            </tr>
    </table>
</div>

在窗口上调用onload

function resolutionIndependent()
        {
            var height;
            var tableMain;
            var divScroll;

            if (document.body && document.body.offsetWidth)
            {
                height = document.body.offsetHeight;
            }
            if (document.compatMode == 'CSS1Compat' && document.documentElement && document.documentElement.offsetWidth)
            {
                height = document.documentElement.offsetHeight;
            }
            if (window.innerWidth && window.innerHeight)
            {
                height = window.innerHeight;
            }
            tableMain = document.getElementById('tableMain');
            divScroll = document.getElementById('divScroll');
            tableMain.style.height = parseFloat(height - 170) + 'px';
            divScroll.style.height = parseFloat(height - 170) + 'px';
            divScroll.style.overflow = "auto";
        }
 //***tableMain which is outer table of divScroll***

我必须制作第一行的固定标题..我添加style="position:fixed"到第一行的每个单元格.但没有得到输出..如何可能

Answer 1

嘿,你甚至可以使用一个简单的jquery函数,它可以在不改变你的HTML代码的情况下为你提供结果

var tdWidth = $("#tableAppointment tbody tr td").width();
$("#tableAppointment thead").css({'position': 'fixed','top': '0','left': '-0.2%', 'background-color': '#f94d4d','color': '#FFFFFF','text-align': 'center','width': '100%'});

$("#tableAppointment thead tr th").width(tdWidth);

工作示例是jsfiddle

我已经为你的问题创建了简单的编码.请参考以下内容来查看它的实际效果:http://jsfiddle.net/john_rock/h6hfX/1/

HTML部分:

<table>
<thead>
<tr><th>Head1</th><th>Head2</th><th>Head3</th><th>Head4</th><th>Head5</th><th>Head6</th></tr>
</thead>
<tfoot>
<tr><td>Foot1</td><td>Foot2</td><td>Foot3</td><td>Foot4</td><td>Foot5</td><td>Foot6</td></tr>
</tfoot>
<tbody>
<tr><td>r1c1</td><td>r1c2</td><td>r1c3</td><td>r1c4</td><td>r1c5</td><td>r1c6</td></tr>
<tr><td>r2c1</td><td>r2c2</td><td>r2c3</td><td>r2c4</td><td>r2c5</td><td>r2c6</td></tr>
<tr><td>r3c1</td><td>r3c2</td><td>r3c3</td><td>r3c4</td><td>r3c5</td><td>r3c6</td></tr>
<tr><td>r4c1</td><td>r4c2</td><td>r4c3</td><td>r4c4</td><td>r4c5</td><td>r4c6</td></tr>
<tr><td>r5c1</td><td>r5c2</td><td>r5c3</td><td>r5c4</td><td>r5c5</td><td>r5c6</td></tr>
<tr><td>r6c1</td><td>r6c2</td><td>r6c3</td><td>r6c4</td><td>r6c5</td><td>r6c6</td></tr>
<tr><td>r7c1</td><td>r7c2</td><td>r7c3</td><td>r7c4</td><td>r7c5</td><td>r7c6</td></tr>
<tr><td>r8c1</td><td>r8c2</td><td>r8c3</td><td>r8c4</td><td>r8c5</td><td>r8c6</td></tr>
<tr><td>r9c1</td><td>r9c2</td><td>r9c3</td><td>r9c4</td><td>r9c5</td><td>r9c6</td></tr>
<tr><td>r10c1</td><td>r10c2</td><td>r10c3</td><td>r10c4</td><td>r10c5</td><td>r10c6</td></tr>
<tr><td>r11c1</td><td>r11c2</td><td>r11c3</td><td>r11c4</td><td>r11c5</td><td>r11c6</td></tr>
<tr><td>r12c1</td><td>r12c2</td><td>r12c3</td><td>r12c4</td><td>r12c5</td><td>r12c6</td></tr>
<tr><td>r13c1</td><td>r13c2</td><td>r13c3</td><td>r13c4</td><td>r13c5</td><td>r13c6</td></tr>
<tr><td>r14c1</td><td>r14c2</td><td>r14c3</td><td>r14c4</td><td>r14c5</td><td>r14c6</td></tr>
<tr><td>r15c1</td><td>r15c2</td><td>r15c3</td><td>r15c4</td><td>r15c5</td><td>r15c6</td></tr>
</tbody>
</table>?

CSS部分:

table {width:100%; border:1px solid #000000;}
thead {background-color:#000268;color:#FFFFFF;text-align:center; position:fixed; top:0px;}
thead th { height:50px; width:120px; text-align:center;border-width: 1px;border-style: outset;}
tbody {color:#000000;text-align:center; height:150px; overflow: scroll; margin:0px;}
tbody td { height:60px; width:100px;border-width: 1px;border-style: outset;}
tfoot {background-color:#000268; color:#FFFFFF;text-align:center; position:fixed; bottom:0px;}
tfoot td { height:50px; width:120px; text-align:center;border-width: 1px;border-style: outset;}?

我认为这可以帮助您解决问题.

注意:这是您问题的示例答案.

尝试 ：

 <thead>
    <tr  style="position: fixed; background-color: grey;">
        <td class="csstextheader" width="70px"></td>
        <td class="csstextheader" width="70px">
            <b>Time Slot&nbsp;</b>
        </td>
        <td><b>Room 7</b></td>
        <td><b>Room 8</b></td>
        <td><b>Room 9</b></td>
        <td><b>Room 10</b></td>
    </tr>
</thead>

将第一行设置为固定位置并使用 css 为所有单元格添加宽度，这样效果会很好
