.SH Description
.\" ====================================================================
.
The
.I hdtbl
macros consist of four base and three optional macros,
controlled by about twenty arguments.
.
The syntax is simple and similar to the HTML table model and nearly as
flexible:
you can write sequences of tokens
(macro calls with their arguments and content data),
separated by blanks and beginning with a macro call,
into the same line to get compact and cleanly arrranged input.
.
An advantage of
.I hdtbl
is that the tables are constructed without calling a preprocessor;
this means that
.IR groff (@MAN7EXT@)'s
full macro capabilities are available.
.
On the other hand,
table processing with
.I hdtbl
is much slower than using the
.IR \%@g@tbl (@MAN1EXT@)
preprocessor.
.
A further advantage is that the HTML-like syntax of
.I hdtbl
will be easily converted to HTML;
this is not implemented yet.
.
.
.\" ====================================================================
.SH Usage
.\" ====================================================================
.
In this and the next section, we present examples to help users
understand the basic workflow of
.IR hdtbl .
.
First of all, you must load the
.I hdtbl.tmac
file.
.
As with nearly all other
.I groff
macro packages,
there are two possibilities to do so:
.
Either add the line
.
.
.PP
.RS
.EX
\&.mso hdtbl.tmac
.EE
.RE
.
.
.PP
to your
.I roff
file before using any macros of the
.I hdtbl
package, or add the option
.
.PP
.RS
.EX
\-m hdtbl
.EE
.RE
.
.
.PP
to the command line of groff (before the document file which contains
.I hdtbl
macros).
.
Then you can include on or more tables in your document, where each one
must be started and ended with the
.CR .TBL
and
.CR .ETB
macros, respectively.
.
.
.PP
In this man page,
we approximate the result of each example as terminal ouput to be as
generic as possible since
.I hdtbl
currently only supports the
.B ps
and
.B pdf
output drivers.
.
.
.PP
The simplest well-formed table consists of just single calls to the
four base table macros in the right order.
.
Here we construct a table with only one cell.
.
.
.PP
.RS
.EX

.EE

Equivalent to the above is the following notation.
.
.
.PP
.RS
.EX
.RI ".TBL .TR .TD \[dq]" "contents of the table cell" "\[dq] .ETB"
.EE
.RE
.
.
.PP
By default, the formatted table is inserted into the surrounding text
at the place of its definition.
.
If the vertical space isn't sufficient, it is placed at the top of
the next page.
.
Tables can also be stored for later insertion.
.
.
.PP
Using
.CIR \[oq]row-number * column-number\[cq]
as the data for the table cells, a table with two rows and two columns
can be written as
.

Here we see a difference from HTML tables: The number of columns must be
explicitly specified using the
.CRI \[oq]cols= m\[cq]
argument (or indirectly via the
.CR \[oq]width\[cq]
argument, see below).
.
.
.PP
The contents of a table cell is arbitrary;
for example,
it can be another table,
without restriction to the nesting depth.
.
A given table layout can be either constructed with suitably nested
tables or with proper arguments to
.CR .TD
and
.CR .TH\c
, controlling column and row spanning.

Note, however, that this table

If a macro has one or more arguments

The order of macro calls and other tokens follows the HTML model.

In the following list, valid predecessors and successors of all

Macro arguments are separated by blanks.

The order of arguments is arbitrary; they are of the form

Argument values specified below as\~\c

Argument values\~\c
.CI m
are natural numbers.

Argument values\~\c
.CI n
are numerical values with the usual

scaling indicators.

Some of the arguments are specific to one or two macros, but most of
them can be specified with

.CR .TR\c

.CR .TD\c

.CR B\c
,
.CR I\c
, or
.CR BI
for roman,
.BR bold ,
.IR italic ,
or \f[BI]bold italic\f[], \" \f[BI] is not portable man(7)
respectively.
.
As with
.IR roff 's
.B .ft
request,
the
.CR \[oq]fst\[cq]
argument can be used to specify the font family and font style together,
for example
.CR \[oq]fst=HNBI\[cq]
instead of
.CR \[oq]ff=HN\[cq]
and
.CR \[oq]fst=BI\[cq]\c
\&.
.
.XDEF
The font style in use right before the table (string
.CR \[oq]t*fst\[cq]\c
).
.
.XAA "fsz=\[aq]" "d1 \[lB]d2\[rB]" \[aq]
A decimal or fractional factor
.CI d1\c
.RI , ""
by which the point size for the table is changed, and
.CI d2\c
.RI , ""
by which the vertical line spacing is changed.
.
If
.CI d2
is omitted, value
.CI d1
is taken for both.
.
.XDEFS "fsz=\[aq]1.0 1.0\[aq]" t*fsz
.
.XAA hal=l\[or]c\[or]b\[or]r
Horizontal alignment of the cell contents in the table.
.
.CR \[oq]hal=l\[cq]\c
: left alignment.
.
.CR \[oq]hal=c\[cq]\c
: centered alignment.
.
.CR \[oq]hal=b\[cq]\c
: both (left and right) alignment.
.
.CR \[oq]hal=r\[cq]\c
: right alignment.
.
.XDEFS hal=b t*hal
.
.XAA val=t\[or]m\[or]b
Vertical alignment of the cell contents in the table for cells lower
than the current row.
.
.CR \[oq]val=t\[cq]\c
: alignment below the top of the cell.
.
.CR \[oq]val=m\[cq]\c
: alignment in the middle of the cell.
.
.CR \[oq]val=b\[cq]\c
: alignment above the cell bottom.
.
.XDEFS val=t t*val
.
.XAA hl=\[lB]s\[or]d\[rB]
Horizontal line between the rows.
.
If specified with
.CR .TD
or
.CR .TH
this is a separator line to the cell below.
.
.CR \[oq]hl=\[cq]
(no value): no separator line.
.
.CR \[oq]hl=s\[cq]\c
: a single separator line between the rows.
.
.CR \[oq]hl=d\[cq]\c
: a double separator line.
.
.IP
The thickness of the separator lines is the half of the border
thickness,
but at least 0.1\~inches.
.
The distance between the double lines is equal to the line thickness.
.
.IP
.B Remark:
Together with
.CR \[oq]border=0\[cq]
for proper formatting the value of
.CR \[oq]csp\[cq]
must be at least .05\~inches for single separator lines and .15\~inches
for double separator lines.
.
.XDEFS hl=s t*hl
.
.XAA vl=\[lB]s\[or]d\[rB]
Vertical separator line between the cells.
.
If specified with
.CR .TD
or
.CR .TH
this is a separator line to the cell on the right.
.
.CR \[oq]vl=s\[cq]\c
: a single separator line between the cells.
.
.CR \[oq]vl=d\[cq]\c
: a double separator line.
.
.CR \[oq]vl=\[cq]
(no value): no vertical cell separator lines.
.

.CR \[oq]hl\[cq]
argument above.

Before creating the first table, you should configure default values
to minimize the markup needed in each table.
.
The following example sets up defaults suitable for typical papers:
.
.
.PP
.RS
.EX
\&.ds t*bgc white\[rs]\[dq] background color
\&.ds t*fgc black\[rs]\[dq] foreground color
\&.ds t*bc black\[rs]\[dq]  border color
\&.nr t*cpd 0.1n\[rs]\[dq]  cell padding
.EE
.RE
.
.
.PP
The file
.I \%@EXAMPLEDIR@/\:hdtbl/\:\%common\:.roff
provides another example setup
in the \[lq]minimal Page setup\[rq] section.
.
.
.PP
A table which does not fit on a partially filled page is printed
automatically on the top of the next page if you append the little
utility macro
.CR t*hm
to the page header macro of your document's main macro package.
.
For example, say
.
.
.PP
.RS
.EX
\&.am pg@top
\&.  t*hm
\&..
.EE
.RE
.
.
.PP
if you use the
.I ms
macro package.
.
.
.PP
The macro
.CR t*EM
checks for held or kept tables,
and for missing
.CR ETB
macros (table not closed).
.
You can append this macro
to the \[lq]end\[rq] macro of your document's main macro package.
.
For example:
.
.
.PP
.RS
.EX
\&.am pg@end-text
\&.  t*EM
\&..
.EE
.RE
.
.
.PP
If you use the
.I ms
macro package.
