如何在PHP中添加背景颜色,以使奇数甚至行



我想在CSS中添加每个奇数行(#e5e8e8)甚至行(#b9b8bb)的背景颜色。

for ($i = 2; $i <= $arrayCount; $i++) {
        $_SESSION["a"] = trim($allDataInSheet[$i]["A"]);
        $_SESSION["b"] = trim($allDataInSheet[$i]["B"]);
        $_SESSION["c"] = trim($allDataInSheet[$i]["C"]);
        $_SESSION["d"] = trim($allDataInSheet[$i]["D"]);
        $_SESSION["e"] = trim($allDataInSheet[$i]["E"]);
        $_SESSION["f"] = trim($allDataInSheet[$i]["F"]);
        $_SESSION["g"] = trim($allDataInSheet[$i]["G"]);

                       echo '<!-- table content - start --> ';
                       echo ' <!-- ROW 1 -->';
                        echo '<tr>';
                            echo '<td width="10" style="border-bottom: 1px solid #ffffff;">';
                                echo '<img src="http://ebiz.pmgasia.com/web/hp/HP_ProTrain_Monthly_eDM/ID/2017/February/images/x.gif" width="10" height="1" style="display:block;border:none;"/>';
                           echo ' </td>';
                            echo '<td width="164" style="border-bottom: 1px solid #ffffff;" valign="middle">';
                                echo '<table width="164" border="0" cellspacing="0" cellpadding="0">';

在这里,我想为每个奇数行(#e5e8e8),甚至在php中添加背景颜色,甚至在php中添加行(#b9b8bb),将我在for loop中编写的这一行中添加。我上面给出的给定表代码是为电子邮件模板创建的。因此,它有很多和奇数,甚至选项都无法正常工作。任何建议。预先感谢

因此,在不深入研究代码的情况下,这是一个一般示例,因为它实际上是一个CSS问题。.因此,为此,您需要使用nth-child()。这是一个例子:

tr:nth-child(odd)		{ background-color:#e5e8e8; }
tr:nth-child(even)		{ background-color:#b9b8bb; }
<table>
    <tr>
        <td> Row 1</td>
    </tr>
    <tr>
        <td>
            Row 2
        </td>
    </tr>
</table>
