我想在左边距中写入数字。包 marginnote 不起作用，大概是因为我使用了 paracol (?) 我目前的解决方案是一个丑陋的宏 \para，它使用 (0,0) 大小的图片和 \llap 在左边距中写入文本。
这种方法有效，但在枚举/逐项列举环境中使用时，无法正确对齐数字。您知道如何确保文本始终处于相同的水平位置吗，比如说文本左侧 0.7 厘米？
非常感谢您提出的任何想法或建议！

此解决方案tikzpagenodes至少对文本区域使用。paracol使用时，它使用\pcol@currcol来确定它位于哪一列。否则，检查当前 x 位置。它可以处理 2 列以上。
请记住，tikz 需要运行两次才能知道它在页面上的位置。
