LaTeX 表格线未连接

Question

我的表格的线条没有连接。
我需要一张每条线条都应连接的表格。

该表的 LaTeX 代码如下：

\begin{table}[]

Answer 1

问题是，在您的代码中，您\multicolumn{2}{}{}在第二列中使用了它，但在第二行中，您在第三列中使用它。这当然是不对齐的。

我假设您提供的代码是由某个表格生成器生成的，而这些表格生成器通常会生成难以阅读且难以维护的代码。因此，我建议您清理代码并删除所有这些不必要的\multicolumn命令。这样事情就会变得容易得多，而且不需要缩放表格，\resizebox这是一种不好的做法，因为它会扭曲字体大小：

为了正确排版减号，您可能需要在相关单元格中使用数学模式（感谢 Mico 的提示）：

Answer 2

我建议您使用tabular*环境来确保表格适合文本块，或者，表格的宽度等于\textwidth。我还会确保 12 个数据列的宽度相等，并将数字与隐含的小数点对齐。哦，我还会删除所有垂直规则，并使用更少但间距适当的水平规则。

我猜你是某些软件的受害者，这些软件声称能为表格生成良好的代码。显然，\multicolumn声明每一个列中的条目。

此外，该软件的列数也错误。

booktabs这是使用和自动调整列间空间大小的另一种实现方式。避免调整大小。
