大佬教程收集整理的这篇文章主要介绍了html – 使用css将按钮与表中的行对齐，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

我正在尝试开发一个可用于编辑数据库信息的表(对于非数据库用户).这是我的(对于 HTML)：

<table id="myTable" cellspacing='0'>
    <tr><th>column 1</th><th>column 2</th><th>column 3</th></tr>
    <tr id='1'><td>1</td><td>1</td><td>2</td>
    <td style=" table-layout:fixed">
     <div style="width:0px;overflow:visible;position:relative">
        <a style="display:block;position:relative;left:20px">-</a>
     </div>
    </td>

    </tr>
    <tr id='2' class='even'><td>3</td><td>5</td><td>8</td></tr>
    <tr id='3'><td>13</td><td>21</td><td>34</td></tr>
    <tr id='4' class='even'><td>55</td><td>89</td><td>144</td></tr>
    <tr id='5'><td>233</td><td>377</td><td>610</td></tr>
</table>
<input class="addRow" type="button" value="+">
</table>

这是CSS：

table {
    BACkground: #E0F5F9;
    margin-left: 20px;
    margin-right: 20px;
    margin-top: 20px;
    margin-bottom: 0px;
    border-style: solid;
    border-width: 2px;
    border-color: #1C9CBc;  
    -moz-border-radius:10px;
    -webkit-border-radius:10px;
    border-radius:10px;
}

table th {
    padding:4px 10px;
    BACkground: #A8A8A8;
}

table td {
    BACkground:#fff;
    padding:2px 10px 4px 10px;
}

div.editableTable {
    display: inline;
}

input.addRow {
    margin-left: 10px;
    border: solid 2px #1C9CBc;
    -moz-border-radius:10px;
    -webkit-border-radius:10px;
    border-radius:10px;
    padding-left: 5px;
    padding-right: 5px;
    BACkground: #A8A8A8;

}

table tr.even td {BACkground:#98E6F9}
table tr td {
    BACkground: #E0F5F9;
}

table tr.ediTing td {
    BACkground: #FF0000;
}

table tr.SELEctedEven td {
    BACkground: #98E6F9;
    border-left-width: 0px;
    border-top-width: 1px;
    border-bottom-width: 1px;
    border-right-width: 0px;
    border-style: solid;
    border-color: #03C100;
}

table tr.SELEctedEven td:first-child {
    border-left-width: 1px;
    border-top-width: 1px;
    border-bottom-width: 1px;
    border-right-width: 0px;
    border-style: solid;
    border-color: #03C100;
    -moz-border-radius-topleft:10px;
    -moz-border-radius-bottomleft:10px;
    -webkit-border-bottom-left-radius:10px;
    border-bottom-left-radius:10px;
    -webkit-border-top-left-radius:10px;
    border-top-left-radius:10px;
}

table tr.SELEctedEven td:last-child {
    border-left-width: 1px;
    border-top-width: 1px;
    border-bottom-width: 1px;
    border-right-width: 0px;
    border-style: solid;
    border-color: #03C100;
    -moz-border-radius-topright:10px;
    -moz-border-radius-bottomright:10px;
}

table tr.SELEctedEven td:last-child {
    border-left-width: 0px;
    border-top-width: 1px;
    border-bottom-width: 1px;
    border-right-width: 1px;
    border-style: solid;
    border-color: #03C100;
}

table tr.SELEcted td {
    /* BACkground: #E0F5F9; */
    border-left-width: 0px;
    border-top-width: 1px;
    border-bottom-width: 1px;
    border-right-width: 0px;
    border-style: solid;
    border-color: #03C100;
}

table tr.SELEcted td:first-child {
    border-left-width: 1px;
    border-top-width: 1px;
    border-bottom-width: 1px;
    border-right-width: 0px;
    border-style: solid;
    border-color: #03C100;
    -moz-border-radius-topleft:10px;
    -moz-border-radius-bottomleft:10px;
    -webkit-border-bottom-left-radius:10px;
    border-bottom-left-radius:10px;
    -webkit-border-top-left-radius:10px;
    border-top-left-radius:10px;
}

table tr.SELEcted td:last-child {
    border-left-width: 1px;
    border-top-width: 1px;
    border-bottom-width: 1px;
    border-right-width: 0px;
    border-style: solid;
    border-color: #03C100;
    -moz-border-radius-topright:10px;
    -moz-border-radius-bottomright:10px;
}

table tr.SELEcted td:last-child {
    border-left-width: 0px;
    border-top-width: 1px;
    border-bottom-width: 1px;
    border-right-width: 1px;
    border-style: solid;
    border-color: #03C100;
}

table tr:last-child td:first-child {
    -moz-border-radius-bottomleft:10px;
    -webkit-border-bottom-left-radius:10px;
    border-bottom-left-radius:10px}

table tr:last-child td:last-child {
    -moz-border-radius-bottomright:10px;
    -webkit-border-bottom-right-radius:10px;
    border-bottom-right-radius:10px
}

而且,这是它的样子：

这很好,除了右侧的删除按钮离行有点偏.这意味着一旦我们添加~13或14行,删除按钮就会从它将要删除的行中移开.因此,用户不清楚当他们点击删除时将确切删除哪一行.

我想找到一些方法,允许我使用CSS将按钮(或者,在这种情况下,几个按钮)与所讨论的表的行对齐.这可能吗？我最初(没有成功)尝试在没有第二个表的情况下执行此操作,但这导致了我当前的情况,其中我有一个用于对齐目的的表仅在实际包含数据的表的右侧.

我面临的一个大问题是,我似乎无法弄清楚如何将某些东西与表格中的行对齐.我可以用jQuery做到这一点,但这看起来像是用锤子敲打螺丝.我承认我在编程方面不像CSS那样经验丰富,所以我通常倾向于查看编程答案.有人可以帮我弄清楚如何正确对齐这些按钮吗？

谢谢！

解决方法

您可以尝试将按钮放在最后一个< td>内.在行中然后将其浮动到右边并提供足够大的负右边距以使其在表外;你还需要在桌子上有一个正的右边距,以确保按钮有空间.

例如：

<table>
    <tbody>
        <tr>
            <td>kdsjfkdsl fds</td>
            <td><span class="killer">X</span>Appropriately architect 24/365 internal or "organic" sources after fully tested portals. Monotonectally leverage exisTing an expanded array of action items before resource maximizing growth strategies. Proactively drive orthogonal ROI before sustainable relationships.</td>
        </tr>
        <tr>
            <td>2193485798435</td>
            <td><span class="killer">X</span>Enthusiastically deploy team building data with e-Business Internal or "organic" sources. Enthusiastically negotiate diverse models for transparent communities. Intrinsicly disseminate just in time markets before vertical paradigms. Authoritatively brand perfoRMANce based web-readiness for error-free growth strategies. Energistically empower customer directed markets with quality data. DisTinctively productivate BACkWARD-compatible potentialities before prospective technology.</td>
        </tr>
    </tbody>
</table>

还有一点CSS(用着色来清楚地显示所有内容)：

table {
    margin-right: 2em;
}
td {
    padding: 5px;
    border: 1px solid green;
}
span.killer {
    float: right;
    margin-right: -1.5em;
    color: red;
    font-weight: bold;
}

我从空中挑选了边距以说明效果,我将为您计算正确的值.
