firefox下rowspan+border+border-collapse的bug

(编辑：jimmy 日期: 2025/2/25 浏览：3 次 )

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：

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。

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><thead><th></th><th>Image</th><th>Insert Heading Here</th><th>Image</th></thead><th>1</th><a href="javascript:;" onclick="showimg('/UploadFiles/2021-04-02/arnie.png');"><img src="/UploadFiles/2021-04-02/arnie.png" alt="firefox下rowspan+border+border-collapse的bug" onmousewheel="return bbimg(this)" onload="javascript:resizepic(this)" border="0"/></a>Data<a href="javascript:;" onclick="showimg('http://msn.mess.be/data/thumbnails/16/arnie.png');"><img src="http://msn.mess.be/data/thumbnails/16/arnie.png" alt="firefox下rowspan+border+border-collapse的bug" onmousewheel="return bbimg(this)" onload="javascript:resizepic(this)" border="0"/></a><th>2</th>Data<th>3</th><a href="javascript:;" onclick="showimg('/UploadFiles/2021-04-02/arnie.png');"><img src="/UploadFiles/2021-04-02/arnie.png" alt="firefox下rowspan+border+border-collapse的bug" onmousewheel="return bbimg(this)" onload="javascript:resizepic(this)" border="0"/></a>Data<a href="javascript:;" onclick="showimg('http://msn.mess.be/data/thumbnails/16/arnie.png');"><img src="http://msn.mess.be/data/thumbnails/16/arnie.png" alt="firefox下rowspan+border+border-collapse的bug" onmousewheel="return bbimg(this)" onload="javascript:resizepic(this)" border="0"/></a><th>4</th>Data<th>5</th><a href="javascript:;" onclick="showimg('/UploadFiles/2021-04-02/arnie.png');"><img src="/UploadFiles/2021-04-02/arnie.png" alt="firefox下rowspan+border+border-collapse的bug" onmousewheel="return bbimg(this)" onload="javascript:resizepic(this)" border="0"/></a>Data<a href="javascript:;" onclick="showimg('http://msn.mess.be/data/thumbnails/16/arnie.png');"><img src="http://msn.mess.be/data/thumbnails/16/arnie.png" alt="firefox下rowspan+border+border-collapse的bug" onmousewheel="return bbimg(this)" onload="javascript:resizepic(this)" border="0"/></a><th>6</th>Data<th>7</th><a href="javascript:;" onclick="showimg('/UploadFiles/2021-04-02/arnie.png');"><img src="/UploadFiles/2021-04-02/arnie.png" alt="firefox下rowspan+border+border-collapse的bug" onmousewheel="return bbimg(this)" onload="javascript:resizepic(this)" border="0"/></a>Data<a href="javascript:;" onclick="showimg('http://msn.mess.be/data/thumbnails/16/arnie.png');"><img src="http://msn.mess.be/data/thumbnails/16/arnie.png" alt="firefox下rowspan+border+border-collapse的bug" onmousewheel="return bbimg(this)" onload="javascript:resizepic(this)" border="0"/></a><th>8</th>Data<th>9</th><a href="javascript:;" onclick="showimg('/UploadFiles/2021-04-02/arnie.png');"><img src="/UploadFiles/2021-04-02/arnie.png" alt="firefox下rowspan+border+border-collapse的bug" onmousewheel="return bbimg(this)" onload="javascript:resizepic(this)" border="0"/></a>Data<a href="javascript:;" onclick="showimg('http://msn.mess.be/data/thumbnails/16/arnie.png');"><img src="http://msn.mess.be/data/thumbnails/16/arnie.png" alt="firefox下rowspan+border+border-collapse的bug" onmousewheel="return bbimg(this)" onload="javascript:resizepic(this)" border="0"/></a><th>10</th>Data</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
