我正在尝试与 groff 合作生成一个表格，其中一个单元格跨越多行。
我试过
.TS BOXED LABEL "Table 1: Use Case 1"
allbox, tab(@);
l l
l ld
l ^ .
Use Case Identifier@UC1
Flow of events@T{1. System prompts for username and password
.br
2. User submits their username and password
T}
.TE
但我收到下面的警告，并且表格渲染不正确。
warning: file `report.mom', around line 55:
table wider than line width
我试图生成如下所示的表格，其中左下角的单元格跨越多行。
我还尝试了其中的一个例子文档，特别是以下一个，我得到了相同的结果table wider than line width warning，并且表格无法正确渲染。 （下面的示例是我链接的页面上的最后一个示例。）
.TS

答案1
根据您所需的输出，以下是tbl代码。请注意，您不需要框选项。
我以为你需要一个大胆的UC1在第一行第二列中，因此在列后缀中使用了 B。
.TS BOXED LABEL "Table 1: Use Case 1"
tab(@);
l lB, l l, l l, l l, l l
lT l, ^, ^, ^, ^.

Use Case Identifier@UC1

答案2
主要问题是T{ 必须位于行尾，就像}T必须位于行首一样。只需更改换行符，您就可以得到：
您可以通过使用w(troff_width)（默认比例为恩斯，字体中“n”字符的近似宽度）。例如，用于l lw(50)第一个格式行给出：
请注意，在文档的示例中，为了使其正常工作，您必须将字符串替换[[circle]]为制表符，正如前面提到的那样。
答案3
我还自己找到了一个解决方案（尽管这与我的示例屏幕截图不像其他解决方案那么匹配）：
.TS BOXED
box, tab(@);
l | l .

这会产生
该部分|中的指示在两列之间放置一条垂直线。l | ltbl
指示在两行之间放置一条水平线_。tbl
指示tab(@)将tbl字符@视为行中单元格之间的分隔符。
表明上面\^的tbl表条目向下跨越该行。
