新命令 dynTable 在子文件中不起作用

Question

我正在尝试在 Overleaf 中编写考试。我正在使用子文件，因此我有一个包含一堆子文件的 MainFile.tex 结构。这一直运行良好。当我想添加一个将显示多项选择答题纸的最终页面时，我遇到了一个问题。此页面包含一个 /newcommand（我在 stackexchange 上找到的代码）。当我编译单个页面时，新命令运行良好 - 我得到以下内容：

然而当我尝试重新编译主页时出现错误

。

我的代码是：

\usepackage{graphicx}
\usepackage{anyfontsize}
\usepackage[margin=2.5cm]{geometry}

\parindent 0em     % no indenting on para
% \printanswers


\usepackage{subfiles}
\newcommand{\tabitem}{~~\llap{\textbullet}~~}
