html - 从给定单元格开始 rowspan 和 colspan 并减少 rowspan 的填充

Question

我正在编写一个动态创建 HTML 表格的 PHP 脚本。

有两件东西丢失了，找不到相关信息。

我想减少 rowspan 单元格的“填充”，它在水平方向上太大了。您可以使用什么来修改内部字符串和单元格末尾之间的间距？

我还想从第 3 行到最后一行开始 rowspan，并从第 3 列到最后一列开始 colspan。这能做到吗？

HTML 源代码，如果您想查看表格的外观:

table,
th,
td {
  border: 1px solid black;
  border-collapse: collapse;
}

<table style="width:50%">
  <tr>
    <th colspan="17">Weight, in Kg</th>
  </tr>
  <tr>
    <th rowspan="11">Height, in cm</th>

Answer 1

创建一个 2x2 “填充” 单元格。然后开始列标签单元格一<tr>之后。您基本上有两个标题行水平运行，因此在第三行中开始垂直标题行 <tr> .

table,
th,
td {
  border: 1px solid black;
  border-collapse: collapse;
}

<table style="width:50%">
  <tr>
    <th colspan="2" rowspan="2"></th>
    <th colspan="17">Weight, in Kg</th>
  </tr>
  <tr>
    <th>40</th>
    <th>45</th>
    <th>50</th>
    <th>55</th>
    <th>60</th>
    <th>65</th>
    <th>70</th>
    <th>75</th>
    <th>80</th>
    <th>85</th>
    <th>90</th>
    <th>95</th>
    <th>100</th>
    <th>105</th>
    <th>110</th>
  </tr>
  <tr>
    <th rowspan="11">Height, in cm</th>

当您说“填充”时，我将其理解为 Wight 两侧到单元格边界的空白区域，单位为千克。如果是这样的话:

1. 增加字体大小，这可能看起来很难看。
2. 增加letter spacing , letter-spacing: 0.25em; ，这可能看起来很丑。

如果您在谈论 100、105 和 110 列中数字后的空格，您可以在上面执行，但我建议让所有列的宽度相同，然后将所有数字居中以使所有内容均等。

请注意，使用这种方法，三位数的空格比两位数的空格少。

table,
th,
td {
  border: 1px solid black;
  border-collapse: collapse;
  text-align: center;
}
th,
td {
  min-width: 1.85rem;
}

或者您可以在列和中心设置特定数量的填充。我个人喜欢上面代码片段的结果。在这里，您可以在数字周围获得一致的空白，同时牺牲相等的列宽。

table,
th,
td {
  border: 1px solid black;
  border-collapse: collapse;
  text-align: center;
}
th,
td {
  padding: 0.125rem 0.25rem;
}
