移动设备上的表格行不会超过100％的宽度

Posted 2021-05-04

我有一张桌子，我正用于网站上的购物篮。这一切都运作良好，但一旦我添加了tfoot，tbody将不会超过容器宽度的100％。

我很确定问题与tfoot有关，但我无法找出答案。我认为这与colspan无法在移动设备上工作有关，因为我隐藏了身体中的一个细胞（所以它是不均匀的）但是没有做任何事情。

这是我的例子：https://codepen.io/moy/pen/KQJdbV

.page {
  margin: 0 auto;
  max-width: 1000px;
}


/**

.basket {

  .basket__head th {
    display: table-cell;
    text-align: center;
    vertical-align: middle;
  }
  .basket__head th:first-child {

任何人都可以发现我错过的东西吗？

我确实希望在tfoot内联2个单元格，但第一个单元格的文本与左侧对齐，最后一个/第二个单元格在右侧。如果这有什么不同？

答案

你有

text-align: right; 

在.basket__foot类中，其中使用colspan = 3的td继承。在你的css文件的末尾添加它，它将在左边对齐它。

.basket__foot p:first-child {
  text-align: left;
}

同时点击ctrl-shift-i并检查标签元素，当你悬停在标签上时会看到元素尺寸
