使用 Tikz 展示考试

这是我的实际文件

在此处输入图片描述

我想要的是下图（见下图），但我不知道怎么做。有人可以帮忙做这个演示吗？我希望左边有 2 厘米的边距用于分级（这里我有 4 厘米），右边有 4.5 厘米的边距，并写上：不要在此栏中写字（在更正期间添加评论）。 在此处输入图片描述

这是我的代码：

答案1

借助该geoemtry包，您可以调整边距大小。在下面的 MWE 中，我还添加了marginpar在右边距中写入文本的功能。最后，我还修改了网格的宽度以自动适应文本块。

以下提供的代码将用网格填充水平可用空间。水平方向仅填充网格步长的倍数。您可以指定line width、网格step、height和color：

编辑：因为有人在不相关的聊天中向我提到了这一点。

以下为 添加了另一个键\gridfill，即height target，它将像 键一样设置总体使用高度height，但实际网格将仅以 的倍数绘制step，因此剩余空间将为空白（填充到顶部）。如果height target大于0pt，它将被使用，并且必须是有效的 TeX 长度（因此需要有效的单位）。
