Graphviz：节点内部方向

Question

以下graphviz代码：

digraph g {

labelloc="t";
label="Feed creation process";

graph [
rankdir = "LR"
];
node [
fontsize = "16"
shape = "record"
];
edge [];


abc [shape=none, margin=0, rankdir=""
label=<
<TABLE BORDER="0" CELLBORDER="1" CELLSPACING="0" CELLPADDING="4">
<TR><TD ROWSPAN="3"><FONT COLOR="red">hello</FONT><BR/>world</TD>
<TD COLSPAN="3">b</TD>
<TD ROWSPAN="3" BGCOLOR="lightgrey">g</TD>
<TD ROWSPAN="3">h</TD>
</TR>
<TR><TD>c</TD>
<TD PORT="here">d</TD>
<TD>e</TD>
</TR>
<TR><TD COLSPAN="3">f</TD>
</TR>
</TABLE>>];
}

给出：

我想将表格方向顺时针旋转90°，这样行就是：

• hello world将位于顶部
• f，'c | d | e and b on the row below, 'c|d|e垂直对齐
• g
• h

例如（文字错误导向！）：

有没有办法在不影响图中节点顺序的情况下旋转节点内部结构？

我玩过HTML COLSPAN和ROWSPAN并得到了：

abc2 [shape=none, margin=0, orientation=120.0,
label=
    <
    <TABLE BORDER="0" CELLBORDER="1" CELLSPACING="0" CELLPADDING="4">
       <TR>
          <TD COLSPAN="3"><FONT COLOR="red">HELLO</FONT><BR/>world</TD>
       </TR>
       <TR>
          <TD ROWSPAN="3">b</TD>
          <TD>c</TD>
          <TD ROWSPAN="3">f</TD>
        </TR>
        <TR>
          <TD PORT="here">d</TD>
        </TR>
        <TR>
          <TD>e</TD>
       </TR>
       <TR>
          <TD COLSPAN="3" BGCOLOR="lightgrey">g</TD>
       </TR>
       <TR>
          <TD COLSPAN="3">h</TD>
       </TR>

    </TABLE>
    >
];
