Graphviz dot:如何更改多记录形状中一条记录的颜色

我有以下点样本。我想在每个记录(表名)的第一部分给出不同的背景和前景色。我找不到任何关于如何为记录执行此操作的示例。基本上我希望sql查询架构图中的表名突出。有人可以帮忙吗?

digraph G {
   rankdir=LR;
   node [shape=record];
   corpus_language [label="corpus_language|<id> id\len\l|<name> name\lEnglist\l|<sentence_count> sentence_count\l1027686\l"];
   corpus_sentence [label="corpus_sentence|<id> id\l1241798\l|<text> text\lBaseball is a sport\l|<creator_id> creator_id\l10859\l|<created_on> created_on\l2006-11-14 17:58:09.303128\l|<language_id> language_id\len\l|<activity_id> activity_id\l11\l|<score> score\l124\l"];   
   corpus_language:id -> corpus_sentence:language_id [arrowhead=normal label=language_id];   
}

我很确定这是不可能的。相反,您应该使用HTML样式标签,这是一种更加开发的记录节点形式。您可以使用<table>标记定义节点,并使用bgcolor="your_color"设置颜色。此处提供了可用颜色列表:http://www.graphviz.org/doc/info/colors.html(您还有RGBA方式,如下所述:http://www.graphviz.org/doc/info/attrs.html#k:color

使用HTML标签,您的示例如下:

digraph G
{
    rankdir = LR;
    node1
    [
        shape = none
        label = <<table border="0" cellspacing="0">
                    <tr><td port="port1" border="1" bgcolor="red">corpus_language</td></tr>
                    <tr><td port="port2" border="1">id: en</td></tr>
                    <tr><td port="port3" border="1">name: Englist</td></tr>
                    <tr><td port="port4" border="1">sentence_count: 1027686</td></tr>
                </table>>
    ]
    node2
    [
        shape = none
        label = <<table border="0" cellspacing="0">
                    <tr><td port="port1" border="1" bgcolor="blue">corpus_sentence</td></tr>
                    <tr><td port="port2" border="1">id: 1241798</td></tr>
                    <tr><td port="port3" border="1">text: Baseball is a sport</td></tr>
                    <tr><td port="port4" border="1">creator_id: 10859</td></tr>
                    <tr><td port="port5" border="1">created_on: 2006-11-14 17:58:09.303128</td></tr>
                    <tr><td port="port6" border="1">language_id: en</td></tr>
                    <tr><td port="port7" border="1">activity_id: 11</td></tr>
                    <tr><td port="port8" border="1">score: 124</td></tr>
                </table>>
    ]
    node1:port2 -> node2:port6 [label="language_id"]
}

结果如下:
