除右下角单元格外，所有表格单元格中的字符是什么？

Question

我该如何摆脱它们呢？

\documentclass[letterpaper,10pt]{memoir}
\usepackage{tabularx}
\usepackage{caption}
\begin{document}
\begin{table}[ht]
\centering
\captionsetup{font={tt,Large}}
\caption*{Summertime Checklist}
\begin{tabularx}{262pt}{l|l|l|l|l|l|l|l|l}
\toprule     &
\texttt{Mo.} &
\texttt{Tu.} &
\texttt{We.} &
\texttt{Th.} &
\texttt{Fr.} &
\texttt{Sa.} &
\texttt{Su.}
\\ 
\midrule
\texttt{GO FISHING} &
| &| &| &| &| &| &| &
\\
\midrule
\texttt{GO CAMPING} &
| &| &| &| &| &| &
\\
\midrule
\end{tabularx}
\end{table}
\end{document}
