html - Firefox 和 IE8 中的 CSS 表格单元格填充问题

Question

我在尝试调整表格布局时遇到了一些严重的问题。在 Firefox 中，我得到奇怪的顶部/底部填充与所有文本不一致。在 Firefox 和 IE8 中，我似乎也无法让我的图标在它们的单元格中显示为垂直居中。

见下图:

这是我的表格 CSS:

table.maxwidth {
    width: 100%;
}

table.standard th {
    color: white;
    font: bold 0.85em Century Gothic;
    padding: 0.6em;
    background-color: #424E4F;
}

table.standard td {
    padding: 0.2em 0.5em;
}

table.standard tr + tr > td {
    border-top: 1px dotted #ccc;
}

table.standard th + th {
    border-left: 1px solid white;
}

table.standard td + td {
    border-left: 1px dotted #ccc;
}

table.standard > tfoot > tr > td {
    border-top: 0.18em solid #424E4F;
    padding: 0.2em 0.5em;
}

table.striped tr.alt td {
    background-color: #eee;
}

table.hover tr:hover td {
    background-color: #e0e0e0;
}

这是我的表格 HTML:

<table class="standard maxwidth striped hover">

    <thead>
        <tr>
            <th class="left">Accessory</th>
            <th class="center">Available</th>
            <th class="right">Options</th>
        </tr>
    </thead>

    <tbody>

        <tr>
            <td class="label"><a href="/mss/Accessory/Edit/4">Mains Charger</a></td>
            <td class="center">

            <img src="/mss/Static/images/icons/tick.png" /></td>
            <td class="right">
            <a href="/mss/Accessory/Archive/4" onclick="if(!confirm('Are you sure you want to archive this Accessory?')) return false;">Archive</a>
            / <a href="/mss/Accessory/Delete/4" onclick="if(!confirm('Are you sure you want to delete this Accessory?\nRelated historical data and reports will be affected!')) return false;">Delete</a>

            </td>
        </tr>

        <tr>
            <td class="label"><a href="/mss/Accessory/Edit/3">Bluetooth Headset</a></td>
            <td class="center">

            <img src="/mss/Static/images/icons/tick.png" /></td>
            <td class="right">
            <a href="/mss/Accessory/Archive/3" onclick="if(!confirm('Are you sure you want to archive this Accessory?')) return false;">Archive</a>

            / <a href="/mss/Accessory/Delete/3" onclick="if(!confirm('Are you sure you want to delete this Accessory?\nRelated historical data and reports will be affected!')) return false;">Delete</a>
            </td>
        </tr>

        <tr>
            <td class="label"><a href="/mss/Accessory/Edit/2">Car Kit</a></td>
            <td class="center">

            <img src="/mss/Static/images/icons/tick.png" /></td>

            <td class="right">
            <a href="/mss/Accessory/Archive/2" onclick="if(!confirm('Are you sure you want to archive this Accessory?')) return false;">Archive</a>
            / <a href="/mss/Accessory/Delete/2" onclick="if(!confirm('Are you sure you want to delete this Accessory?\nRelated historical data and reports will be affected!')) return false;">Delete</a>
            </td>
        </tr>

        <tr>
            <td class="label"><a href="/mss/Accessory/Edit/1">Leather Phone Case</a></td>

            <td class="center">

            <img src="/mss/Static/images/icons/tick.png" /></td>
            <td class="right">
            <a href="/mss/Accessory/Archive/1" onclick="if(!confirm('Are you sure you want to archive this Accessory?')) return false;">Archive</a>
            / <a href="/mss/Accessory/Delete/1" onclick="if(!confirm('Are you sure you want to delete this Accessory?\nRelated historical data and reports will be affected!')) return false;">Delete</a>
            </td>
        </tr>


    </tbody>
    <tfoot>
        <tr>
            <td colspan="3"><a href="/mss/Accessory/New">Add an Accessory</a></td>
        </tr>
    </tfoot>
</table>

请注意，单元格内容之前和/或之后的间距似乎不会对问题产生正面或负面影响。

将 CSS 更改为使用 px 单位而不是 em 修复了左列文本的慢跑，但没有解决垂直图像居中问题。想法？

图像是vertically aligned在基线上为后裔留出空间 - 以防万一您添加文本。垂直对齐底部，多余的空间消失。

td img {vertical-align:bottom;}
