bg图像在表头中的定位

Question

如何使用css实现以下功能（背景颜色与背景图像重叠标题行）：

这是表格中TH细胞的一部分。 TH行的颜色为＃0098da，TH单元格的末尾为图像（图像的网址为http://tax.allfaces.lv/templates/tax/images/pg_arrow.png）。

我试图在TH中使用bg图像定位div，但我遇到的问题是图像应该与TH边界重叠。结果我得到了以下信息：

HTML：

    <table id="duration-of-refund" border="0">
    <tbody>
        <tr>
            <th>
                <p>Purchases in Webshops</p>
                <div class="img-at">&nbsp;</div>
            </th>
            <th>
                <p>Currency conversion, Refund transfer</p>
                <div class="img-arrow">&nbsp;</div>
            </th>
        </tr>
        <tr>
            <td>
                <p>Some text here Some text here Some text here Some text here Some text here</p>
            </td>
            <td>
                <p>Some text here Some text here Some text here Some text here Some text here</p>
            </td>
        </tr>
    </tbody>
</table>

CSS：

    #duration-of-refund td {
     width: 400px;
 }
 #duration-of-refund th {
     font-size: 21px;
     color: white;
     text-align: left;
     height: 84px;
     max-height: 84px;
 }
 #duration-of-refund tr th:nth-child(1) {
     background-color: #0098da;
 }
 #duration-of-refund tr th:nth-child(2) {
     background-color: #1F5CA9;
 }
 #duration-of-refund tr th:nth-child(1) p, #duration-of-refund tr th:nth-child(2) p {
     width: 190px;
     float: left;
 }
 .img-at, .img-arrow {
     width: 83px;
     height: 84px;
     float: right;
     margin-right: 20px;
     position: relative;
     top: -20px;
 }
 .img-arrow {
     background-image: url(http://tax.allfaces.lv/templates/tax/images/pg_arrow.png);
 }
 .img-at {
     background-image: url(http://tax.allfaces.lv/templates/tax/images/pg_at.png);
 }
 #duration-of-refund tr td:nth-child(2) {
     background-color: #cceaf8;
 }
}

我认为，这应该是另一种方法。

请给我一些线索如何实现这一目标？我还有其他具有不同图像的TH细胞以相同的方式定位。

试试这个 将图像类标记放在另一个div中并将样式应用为

 float:right;margin-right:90px

和图像位置为绝对

 position: absolute;
