为什么在某些TD / TR的Firefox边界底部更胖？

Question

在Firefox中，为什么某些<td>和<tr>元素的底部边框更胖？在Chrome和Opera中，它运行良好。

table.mytable td {
  border: 1px solid black;
}

<table class="mytable">
  <tr>
    <td>11111</td>
    <td>11111</td>

第一，第五和第九个TRs边界底部更胖。

如果我在标签表中使用属性border = 1，它的效果就差了。

编辑：在Firefox中我有100％的尺寸/缩放屏幕。

试试这个代码段。我希望这能帮到您。我已经检查了 Firefox ，它的工作正常（Windows-10）
