如何使用Unix实用程序拥有多行单元格？

Question

我试图使用groff来生成一个单元格跨多行的表。

我试过了

.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

但是我得到了下面的警告，表呈现的不正确。

warning: file `report.mom', around line 55:
  table wider than line width

我试图生成如下所示的表，其中左下角的单元格跨越多个行。

我还尝试了文献资料中的一个示例，特别是下面的示例，得到了相同的table wider than line width warning，表没有正确地呈现。(下面的示例是我链接的页面上的最后一个示例。)

.TS
box;
cb s s s
c | c | c s
ltiw(1i) | ltw(2i) | lp8 | lw(1.5i)p8.

Answer 1

根据所需的输出，下面将是tbl代码。请注意，您不需要框选项。

我假设第二列中需要粗体的UC1，所以在后缀中使用了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
_
Title@Login
_
Participating actor(s)@Dental staff member or client
_
Precondition(s)@System is ready to receive requests
_
Parameters@Username, password
_
T{
Flow of events
T}@1. System prompts for username and password
^@2. User submits their username and password
^@3. System logs user in
^@4. User is redirected to homepage
_
.TE

Answer 2

主要的问题是T{ <#>必须在行的末尾，就像}T必须位于行的开头一样。只要更改换行符，您就可以得到：

您可以通过使用w(troff_width)为列提供宽度来帮助排版(默认刻度是ens，字体中"n“字符的大致宽度)。例如，对第一个格式行使用l lw(50)提供：

请注意，在文档中的示例中，要使其工作，必须将字符串[[circle]]替换为选项卡字符，正如前面提到的那样。

Answer 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 .
Use Case Identifier@UC1
_
Title@Login
_
Participating actor(s)@Dental staff member or client
_
Precondition(s)@System is ready to receive requests
_
Parameters@Username, password
_
Flow of events@1. System prompts for username and password
\^@2. User submits their username and password
\^@3. System logs user in
\^@4. User is redirected to homepage
.TE

这会产生

|在l | l部分告诉tbl在两列之间放置一条垂直线。

_告诉tbl在两行之间放置一条水平线。

tab(@)告诉tbl将@字符视为行中单元格之间的分隔符。

\^告诉tbl，紧接在上面的表条目向下跨越该行。
