我正在编写一个动态创建HTML表的PHP脚本。
有两件事缺少，无法找到信息。
我想减少rowspan单元的"填充"，水平太大。您可以使用什么来修改单元内部和末端的字符串之间的间距？
我也想从3行开始到最后一排，然后从第3列开始Colspan到最后一个。可以做到吗？
html源代码，如果您想查看表的样子：
table,
th,
td {
border: 1px solid black;
border-collapse: collapse;
}<table style="width:50%">

<th colspan="17">Weight, in Kg</th>

<th rowspan="11">Height, in cm</th>

</table>创建一个2x2 "填充" 单元格。然后在后来启动列标签单元格一个<tr>。基本上，您可以水平运行两个标头行，因此在第三个<tr>中启动垂直标头行。

</table>当您说"填充" 时，我将其理解为 Wight两侧的空白，以kg 在单元的边界中。如果是这样：
- 增加字体尺寸，看起来可能很难。
- 增加字母间距，
letter-spacing: 0.25em;，看起来很丑。
如果您是在谈论> 100 中的数字之后的空白'd建议让所有列都具有相同的宽度，然后将所有数字居中以甚至所有数字。
请注意，使用此方法的三位数的空间比双位数少。
