后查具体情况概述为：firefox+table rowspan+border+border-collapse:collapse;
表现情况是：第一行与最后一行正常，其余的中间行，全部都与预期的border不同。
先看示例吧：

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd"><html><head><title>Rank's HTML document</title><meta http-equiv="Content-Type" content="text/html; charset=gb2312"><meta http-equiv="Pragma" content="no-cache"><meta http-equiv="Cache-Control" content="no-cache"><meta http-equiv="Expires" content="0"><meta http-equiv="ImageToolbar" content="no"><meta http-equiv="Creator.name" content="rank"><style type="text/css" title="default" media="screen"></style></head><body><style>* {font-size:15px;text-decoration:none;}td {border-top:1px solid #000}</style><table width="50%" border="0" style="border:1px solid #000;border-collapse:collapse;width:100%;"><tr><th width="49%">第一列</th><th width="50%">第二列</th></tr><tr class=""><td> test </td><td rowspan="2"><a href="#">第一条中间没有横线</a> </td></tr><tr class=""><td>test</td></tr><tr class="zebra"><td> test </td><td rowspan="2"><a href="#">可爱的firefox让我们看到了两条线</a> </td></tr><tr class="zebra"><td>test</td></tr><tr class=""><td> test </td><td rowspan="2"><a href="#">可爱的firefox让我们看到了两条线</a> </td></tr><tr class=""><td>test</td></tr><tr class="zebra"><td> test </td><td rowspan="2"><a href="#">可爱的firefox让我们看到了两条线</a> </td></tr><tr class="zebra"><td>test</td></tr><tr class=""><td> test </td><td rowspan="2"><a href="#">最后一条中间没有横线</a> </td></tr><tr class=""><td>test</td></tr></table></body></html>

经过验证，两种解决方法。
去除border-collapse
加上一个border-left或者border-right
无独有偶，后来搜索了一下，也有前人踩到了这个坑里，它的解决方法也是：border-left:1px solid #999 important;border-left:none的方法来解决。
(see detail:http://www.experts-exchange.com/Web_Development/Web_Languages-Standards/CSS/Q_23698654.html)
好在可以通过border的错觉及颜色来解决这个问题。为了偷懒，我直接用上了对方的e.g。看解决前的代码：

<html><head><style type="text/css">table {border-collapse:collapse;}th, td {border: 1px black solid;}th {background-color: #A9AE7B;}td.right_user_img {border-left:none;background-color: #999999;text-align: center;padding: 15px;}td.left_user_img {border-right: none;background-color: #CCCCCC;text-align: center;padding: 15px;}td.left_image_join {background-color: #CCCCCC;border-left: none;}td.right_image_join {background-color: #999999;border-right: none;}img {border: none;}</style></head><body><table cellspacing="0px" cellpadding="5px"><thead><tr><th></th><th>Image</th><th>Insert Heading Here</th><th>Image</th></tr></thead><tbody><tr><th>1</th><td rowspan="2" class="left_user_img"><img src="/uploads/allimg/210413/1153041a1-0.png"></td><td class="left_image_join">Data</td><td rowspan="2" class="right_user_img"><img src="/uploads/allimg/210413/1153041a1-0.png"></td></tr><tr><th>2</th><td class="right_image_join">Data</td></tr><tr><th>3</th><td rowspan="2" class="left_user_img"><img src="/uploads/allimg/210413/1153041a1-0.png"></td><td class="left_image_join">Data</td><td rowspan="2" class="right_user_img"><img src="/uploads/allimg/210413/1153041a1-0.png"></td></tr><tr><th>4</th><td class="right_image_join">Data</td></tr><tr><th>5</th><td rowspan="2" class="left_user_img"><img src="/uploads/allimg/210413/1153041a1-0.png"></td><td class="left_image_join">Data</td><td rowspan="2" class="right_user_img"><img src="/uploads/allimg/210413/1153041a1-0.png"></td></tr><tr><th>6</th><td class="right_image_join">Data</td></tr><tr><th>7</th><td rowspan="2" class="left_user_img"><img src="/uploads/allimg/210413/1153041a1-0.png"></td><td class="left_image_join">Data</td><td rowspan="2" class="right_user_img"><img src="/uploads/allimg/210413/1153041a1-0.png"></td></tr><tr><th>8</th><td class="right_image_join">Data</td></tr><tr><th>9</th><td rowspan="2" class="left_user_img"><img src="/uploads/allimg/210413/1153041a1-0.png"></td><td class="left_image_join">Data</td><td rowspan="2" class="right_user_img"><img src="/uploads/allimg/210413/1153041a1-0.png"></td></tr><tr><th>10</th><td class="right_image_join">Data</td></tr></tbody></table></body></html>

解决后的代码：

<html><head><style type="text/css">table {border-collapse:collapse;}th, td {border: 1px black solid;}th {background-color: #A9AE7B;}td.right_user_img {border-left:1px solid #999999 !important; /*this solves border-collapse/rowspan bug in firefox 3 */border-left:none;background-color: #999999;text-align: center;padding: 15px;}td.left_user_img {border-right: none;background-color: #CCCCCC;text-align: center;padding: 15px;}td.left_image_join {background-color: #CCCCCC;border-left: none;}td.right_image_join {background-color: #999999;border-right: none;}img {border: none;}</style></head><body><table cellspacing="0px" cellpadding="5px"><thead><tr><th></th><th>Image</th><th>Insert Heading Here</th><th>Image</th></tr></thead><tbody><tr><th>1</th><td rowspan="2" class="left_user_img"><img src="/uploads/allimg/210413/1153041a1-0.png"></td><td class="left_image_join">Data</td><td rowspan="2" class="right_user_img"><img src="/uploads/allimg/210413/1153041a1-0.png"></td></tr><tr><th>2</th><td class="right_image_join">Data</td></tr><tr><th>3</th><td rowspan="2" class="left_user_img"><img src="/uploads/allimg/210413/1153041a1-0.png"></td><td class="left_image_join">Data</td><td rowspan="2" class="right_user_img"><img src="/uploads/allimg/210413/1153041a1-0.png"></td></tr><tr><th>4</th><td class="right_image_join">Data</td></tr><tr><th>5</th><td rowspan="2" class="left_user_img"><img src="/uploads/allimg/210413/1153041a1-0.png"></td><td class="left_image_join">Data</td><td rowspan="2" class="right_user_img"><img src="/uploads/allimg/210413/1153041a1-0.png"></td></tr><tr><th>6</th><td class="right_image_join">Data</td></tr><tr><th>7</th><td rowspan="2" class="left_user_img"><img src="/uploads/allimg/210413/1153041a1-0.png"></td><td class="left_image_join">Data</td><td rowspan="2" class="right_user_img"><img src="/uploads/allimg/210413/1153041a1-0.png"></td></tr><tr><th>8</th><td class="right_image_join">Data</td></tr><tr><th>9</th><td rowspan="2" class="left_user_img"><img src="/uploads/allimg/210413/1153041a1-0.png"></td><td class="left_image_join">Data</td><td rowspan="2" class="right_user_img"><img src="/uploads/allimg/210413/1153041a1-0.png"></td></tr><tr><th>10</th><td class="right_image_join">Data</td></tr></tbody></table></body></html>

PS.好象firefox 一直以来就有这个bug。问多久前有的？至少flock就有了
