感谢@ZhiyuanLck 的回答。这是一个最小工作示例,
\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{shapes.geometric, patterns}
\tikzstyle{block} = [rectangle, minimum width=3cm, minimum height=1cm, text centered, text width=3cm, draw=black, pattern color=blue, pattern = north east lines]
\begin{document}
\begin{tikzpicture}[node distance =2cm]
\node (test) [block] {\textbf{Hashed Fill}} ;
\end{tikzpicture}
\end{document}
