css双单元格边框

问题描述

谁能解释一下为什么我在简单的表格上每 2-5 行看到 2px 的底部边框。 似乎问题取决于显示器，它在某些显示器上消失。在某些监视器中，仅当我在浏览器中缩放内容时才会出现。但为什么？我强烈使用：

border-bottom:1px solid #ccc; border-collapse: collapse;

恕我直言，边框的厚度应始终为 1px（如果缩放内容，则为 2px）。但是一些1px的边框和一些2px的边框看起来很奇怪很脏。

示例：

table {
    border-collapse: collapse;
    border-spacing: 0;
    box-sizing: border-box;
}
table,table tr,table tr td {
    border: none;
}
table tr td {
    border-bottom: 1px solid #ccc;
}
