我的数字无法并排放置

我有此代码将六幅图像分成两行（每行 3 幅图像）：

\begin{figure}[htbp!]   
 \centering
 \begin{subfigure}[b]{0.3 \textwidth}

     \includegraphics[width=\textwidth]{1agw-eva.png}
     \caption{Cec\_2021\_ Function 1}
 \end{subfigure} \hfill
 
 \begin{subfigure}[b]{0.3\textwidth}
     \includegraphics[width=\textwidth]{2agw-eva.png}
     \caption{Cec\_2021\_ Function 2}
 \end{subfigure} \hfill

 \begin{subfigure}[b]{0.3\textwidth}
     \includegraphics[width=\textwidth]{3agw-eva.png}
     \caption{Cec\_2021\_ Function 3}
 \end{subfigure}

 \begin{subfigure}[b]{0.3\textwidth}
     \includegraphics[width=\textwidth]{4agw-eva.png}
     \caption{Cec\_2021\_ Function 5}
 \end{subfigure} \hfill


 \begin{subfigure}[b]{0.3\textwidth}

     \includegraphics[width=\textwidth]{5agw-eva.png}
     \caption{Cec\_2021\_ Function 7}
 \end{subfigure} \hfill


 \begin{subfigure}[b]{0.3\textwidth}
     \centering
     \includegraphics[width=\textwidth]{6agw-eva.png}
     \caption{Cec\_2021\_ Function 8}
 \end{subfigure}
 \hfill

 \begin{subfigure}[t]{0.9\textwidth}
     \centering
     \includegraphics[width=\textwidth]{7agw-eva.png}
     \caption{Cec\_2021\_ Function 3}
 \end{subfigure}

    \caption{caption.}
    \label{fig:fig-evaluation}
\end{figure}

但它们是以垂直位置显示的。

这很好用。请小心处理空白行，因为它们会开始一个新段落，所以以 结尾的行不应该有空白行\hfill。
