TikZ 中带有文本的单元格略微凸起

Question

从下图可以看出，只有带有文本的单元格比空单元格略微凸起。

我希望所有单元格都处于同一级别。我该怎么做？以下是我的工作代码：

\begin{tikzpicture}
[array/.style={matrix of nodes,
nodes={draw, minimum size=10mm, minimum width=15mm, fill=gray!10},
column sep=-\pgflinewidth, 
row sep=0.5mm, 
nodes in empty cells, 
row 1 column 1/.style={nodes={draw=none}},
row 2 column 1/.style={nodes={draw=none, fill=none}},
row 2 column 2/.style={nodes={draw=none, fill=none}},
row 2 column 8/.style={nodes={draw=none, fill=none}},
row 2 column 9/.style={nodes={draw=none, fill=none}},
row 5 column 4/.style={nodes={draw=none, fill=none}},
row 5 column 5/.style={nodes={draw=none, fill=none}},
row 5 column 6/.style={nodes={draw=none, fill=none}},
row 1/.style={nodes={font=\ttfamily, draw=none, fill=none, minimum size=5mm}}, 
row 3/.style={nodes={font=\ttfamily, draw=none, fill=none, minimum size=5mm}}, 
row 4/.style={nodes={font=\ttfamily, draw=none, fill=none, minimum size=5mm}}, 
}]

\matrix[array] (array) 
{ 
    &   &   &   &   dhaka   &   &   &   &       \\
    &   &   &   &   19      &   &   &   &       \\
    &   &   & 20021 &   20022 & 20023 & &   &       \\
    &   sylhet  &   &   &           &   &   &   khulna  &       \\
    & 19    &   &   &           &   &   &   20022 &     \\
}; 


\draw [-{Latex[length=3mm]}]  (array-2-5.south)--(array-5-8.north) node [midway, above, sloped] (TextNode) {\hspace{1.5cm} \&}; 
\draw [-{Latex[length=3mm]}]  (array-2-5.south)--(array-5-2.north); 

\end{tikzpicture}

Answer 1

添加anchor=north节点定义

如下

[mat/.style={matrix of nodes,
            nodes={draw, minimum size=10mm, minimum width=15mm, fill=gray!10,   anchor=north, },

输出是

还稍微改变了箭头的选项

\draw [-{Latex[length=3mm]}]  (array-2-5.south)--(array-5-8.north) node [near end, above, sloped] (TextNode) {\&}; 

取而代之midway的是near end现在没有要求hspace

平均能量损失
