爲什麼在某些TDs/TRs的Firefox邊界底部更胖？

Question

在Firefox中，爲什麼一些<td>和<tr>元素中的底部邊界更胖？在Chrome和Opera中，它運行良好。

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

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

第一之後，第五和第九的TR邊框底部爲胖。

如果我在標記表中使用屬性border = 1，它的工作原理也一樣糟糕。

編輯：在Firefox中，我有100％的大小/縮放屏幕。

試試這個片段。我希望這能幫到您。我已經在檢查火狐其工作語言（Windows-10）

table.mytable{ 
 
border-collapse: collapse; 
 
} 
 
table.mytable td { 
 
border: 1px solid black; \t 
 
}
