如何枚举框？

Question

\newcommand\answerboxb{%%
\fbox{\rule{0.3in}{16pt}\rule[-0.5ex]{0pt}{4ex}}}

\newcommand\answerboxw{%%
\fbox{\rule{0.3in}{0pt}\rule[-0.5ex]{0pt}{4ex}}}
.....
\centerline \answerboxb  \answerboxb  \answerboxb \answerboxw \answerboxw \answerboxw \answerboxw  \\ 
\centerline 1 2 3 4 5 6 7

我想枚举这 7 个框，但我无法对齐它们。我尝试添加空格、居中等等，但都无济于事。

这是你想要的吗？

\documentclass{report}
\newcommand\answerboxb{%%
\fbox{\rule{0.3in}{16pt}\rule[-0.5ex]{0pt}{4ex}}}

\newcommand\answerboxw{%%
\fbox{\rule{0.3in}{0pt}\rule[-0.5ex]{0pt}{4ex}}}
\begin{document}
\begin{center}
\begin{tabular}{ccccccc}
 \answerboxb & \answerboxb & \answerboxb & \answerboxw & \answerboxw & \answerboxw & \answerboxw  \\ 
 1 & 2 & 3 & 4 & 5 & 6 & 7
\end{tabular}
\end{center}
\end{document}
