将多维数组数据输出为表格

问题描述 投票：0回答：1

我有一个多维数组，如下所示。我想在表格中显示数据，将一周中的每一天及其开始和结束时间显示在一行中。下表附有预期结果。

我对数组不熟悉，所以我还没有真正尝试过任何值得一提的东西。非常感谢您的帮助。非常感谢。

你可以这样做。请阅读代码中的注释以及输出下面的注释。

测试一下这里。

注释

我重新打包了初始数组，以便更轻松地循环它并生成稍后渲染的 HTML 字符串。如果您控制初始表（我在提供的代码中称为 

$times
的表）的形成方式，则可以避免重新打包。

渲染的 HTML 表是一个准系统表 - 您可以在循环遍历它时提供 CSS 类，或者在包含 

$html
和 
thead
的 
tbody
变量的开头部分提供。

此外，如果您需要设置非空（或空）表格单元格的样式，也可以使用 CSS 类来实现。

一些注意事项

所提供的建议假设工作时间始终分为两部分。考虑到这一假设，该用法的范围受到一定限制 - 它不涵盖只有单一工作时间的情况（例如，每天上午 9 点到下午 5 点，仅此而已），也不涵盖有工作时间的情况。是三、四或 n 部分的工作时间。

考虑到这一点，代码可以通过几种方式进行概括（我不会这样做，因为你实际上并不需要它，但会提供一个总体轮廓）：

  1. 可以将 
    th
    的数量动态化，而不是使用硬编码的表头，只需找到最大的 
    opening_time
    数组，然后使用简单的 
    th
    循环创建这些额外的 
    for
  2. 这也将在稍后如何生成 
    td
    时应用，因为它们不会是 3 个，而是 1 + n，其中 n 是最大 
    opening_time
    数组的大小
  3. 检查一天中的第一部分、第二部分或第 n 部分是否设置了时间，最好使用某种函数，而不是依赖于对一天中各个部分进行一系列
    if/else
    检查
