如何将数据结构数组的空单元格与填充单元格对齐？

Question

我正在尝试将数据结构中的数组的空单元格与已填充单元格对齐。请帮忙！！这是我目前拥有的代码：

\documentclass[tikz,border=2mm]{standalone}
\usetikzlibrary{matrix,backgrounds}

\begin{document}
\begin{tikzpicture}
\matrix (m) [matrix of nodes,
             nodes={draw, minimum size=8mm},
             nodes in empty cells,
             row 1/.style={nodes={draw=none}},]
{
  0 & 1 & 2 & 3 & 4 & 5 & 6 & 7 \\
  2 & 4 & 4 & 5 &  &  &  & &\\
};
\end{tikzpicture}
\end{document}

结果如下：

我想把盒子排列整齐，该怎么做呢？？？

您需要定义节点的锚点

\documentclass[tikz,border=2mm]{standalone}
\usetikzlibrary{backgrounds, matrix}

\begin{document}
\begin{tikzpicture}
\matrix (m) [matrix of nodes,
             nodes={draw, minimum size=8mm, anchor=south},     % <-- added anchor
             column sep=-\pgflinewidth, row sep=-\pgflinewidth, % <-- for overlaps cells borders
             nodes in empty cells,
             row 1/.style={nodes={draw=none}}
             ]
{
  0 & 1 & 2 & 3 & 4 & 5 & 6 & 7 \\
  2 & 4 & 4 & 5 &   &   &   &   \\
};
\end{tikzpicture}
\end{document}
