    Command:

    tbl

    
    
    

    SYNOPSIS

           tbl [ -Cv ] [ files... ]
    
    
    

    DESCRIPTION

           This manual page describes the GNU version of tbl, which is part of the
           groff document formatting system.  tbl compiles descriptions of  tables
           embedded  within troff input files into commands that are understood by
           troff.  Normally, it should be invoked using the -t  option  of  groff.
           It is highly compatible with Unix tbl.  The output generated by GNU tbl
           cannot be processed with Unix troff; it  must  be  processed  with  GNU
           troff.   If  no files are given on the command line, the standard input
           will be read.  A filename of - will cause  the  standard  input  to  be
           read.
    
    
    

    OPTIONS

           -C     Recognize  .TS  and  .TE even when followed by a character other
                  than space or newline.
    
           -v     Print the version number.
    
    
    

    USAGE

           tbl expects to find table descriptions wrapped in the .TS (table start)
           and  .TE  (table  end)  macros.  The line immediately following the .TS
           macro may contain any of the following  global  options  (ignoring  the
           case of characters -- Unix tbl only accepts options with all characters
           lowercase or all characters uppercase):
    
           center Centers the table (default is left-justified).  The  alternative
                  keyword name centre is also recognized (this is a GNU tbl exten-
                  sion).
    
           delim(xy)
                  Use x and y as start and end delimiters for eqn(1).
    
           expand Makes the table as wide as the current line length.
    
           box    Encloses the table in a box.
    
           doublebox
                  Encloses the table in a double box.
    
           allbox Encloses each item of the table in a box.
    
           frame  Same as box (GNU tbl only).
    
           doubleframe
                  Same as doublebox (GNU tbl only).
    
           tab(x) Uses the character x instead of a tab to  separate  items  in  a
                  line of input data.
    
           linesize(n)
    
           The  global  options must end with a semicolon.  There might be whites-
           pace after an option and its argument in parentheses.
    
           After global options come lines describing the format of each  line  of
           the  table.   Each  such  format  line  describes one line of the table
           itself, except that the last format line (which you  must  end  with  a
           period) describes all remaining lines of the table.  A single key char-
           acter describes each column of each line of the  table.   You  may  run
           format specs for multiple lines together on the same line by separating
           them with commas.
    
           You may follow each key character with specifiers  that  determine  the
           font  and  point  size of the corresponding item, that determine column
           width, inter-column spacing, etc.
    
           The longest format line defines the number of  columns  in  the  table;
           missing format descriptors at the end of format lines are assumed to be
           'L'.  Extra columns in the data (which  have  no  corresponding  format
           entry) are ignored.
    
           The available key characters are:
    
           c,C    Centers item within the column.
    
           r,R    Right-justifies item within the column.
    
           l,L    Left-justifies item within the column.
    
           n,N    Numerically  justifies  item  in  the column: Units positions of
                  numbers are aligned vertically.
    
           s,S    Spans previous item on the left into this column.
    
           a,A    Centers longest line in this column and then left-justifies  all
                  other lines in this column with respect to that centered line.
    
           ^      Spans down entry from previous row in this column.
    
           _,-    Replaces this entry with a horizontal line.
    
           =      Replaces this entry with a double horizontal line.
    
           |      The  corresponding  column  becomes  a  vertical rule (if two of
                  these are adjacent, a double vertical rule).
    
           A vertical bar to the left of the first key-letter or to the  right  of
           the last one produces a line at the edge of the table.
    
           Here  are the specifiers that can appear in suffixes to column key let-
           ters:
    
                  A vertical line spacing specifier followed by a  column  separa-
                  tion  number must be separated by one or more blanks.  No effect
                  if the corresponding table entry isn't a text block.
    
           f,F    Either of these specifiers  may  be  followed  by  a  font  name
                  (either  one  or  two  characters  long),  font number (a single
                  digit), or long name in parentheses (the last form is a GNU  tbl
                  extension).   A one-letter font name must be separated by one or
                  more blanks from whatever follows.
    
           p,P    Followed by a number, this does a  point  size  change  for  the
                  affected  fields.   If  signed, the current point size is incre-
                  mented or decremented (using a signed number instead of a signed
                  digit  is a GNU tbl extension).  A point size specifier followed
                  by a column separation number must be separated by one  or  more
                  blanks.
    
           w,W    Minimal  column  width  value.   Must  be  followed  either by a
                  troff(1) width expression in parentheses or a unitless  integer.
                  If  no  unit  is  given,  en  units  are used.  Also used as the
                  default line length for included text blocks.  If used  multiple
                  times, the last entry takes effect.
    
           e,E    Make equally-spaced columns.
    
           u,U    Move the corresponding column up one half-line.
    
           z,Z    Ignore  the corresponding column for width-calculation purposes.
    
           A number suffix on a key character is interpreted as a  column  separa-
           tion  in  ens  (multiplied  in  proportion if the expand option is on).
           Default separation is 3n.
    
           The format lines are followed by lines containing the actual  data  for
           the  table, followed finally by .TE.  Within such data lines, items are
           normally separated by tab characters (or the character  specified  with
           the  tab option).  Long input lines can be broken across multiple lines
           if the last character on the line is '\' (which vanishes after concate-
           nation).
    
           A dot starting a line, followed by anything but a digit is handled as a
           troff command, passed through without changes.  The table  position  is
           unchanged in this case.
    
           If  a  data  line consists of only '_' or '=', a single or double line,
           respectively, is drawn across the table at that point; if a single item
           in  a data line consists of only '_' or '=', then that item is replaced
           by a single or double line, joining its neighbours.   If  a  data  item
           consists  only  of '\_' or '\=', a single or double line, respectively,
           is drawn across the field at that point which does not join its  neigh-
           bours.
    
           global options) similar to the .TS request.
    
    
    

    INTERACTION WITH EQN

           tbl(1)  should  always  be called before eqn(1) (groff(1) automatically
           takes care of the correct order of preprocessors).
    
    
    

    GNU TBL ENHANCEMENTS

           There is no limit on the number of columns in a table, nor any limit on
           the  number of text blocks.  All the lines of a table are considered in
           deciding column widths, not just the  first  200.   Table  continuation
           (.T&) lines are not restricted to the first 200 lines.
    
           Numeric and alphabetic items may appear in the same column.
    
           Numeric and alphabetic items may span horizontally.
    
           tbl uses register, string, macro and diversion names beginning with the
           digit 3.  When using tbl you should avoid  using  any  names  beginning
           with a 3.
    
    
    

    BUGS

           You should use .TS H/.TH in conjunction with a supporting macro package
           for all multi-page boxed tables.  If there is no header that  you  wish
           to  appear  at  the  top  of each page of the table, place the .TH line
           immediately after the format section.  Do not enclose a multi-page  ta-
           ble within keep/release macros, or divert it in any other way.
    
           A text block within a table must be able to fit on one page.
    
           The bp request cannot be used to force a page-break in a multi-page ta-
           ble.  Instead, define BP as follows
    
                  .de BP
                  .ie '\\n(.z'' .bp \\$1
                  .el \!.BP \\$1
                  ..
    
           and use BP instead of bp.
    
           Using \a directly in a table to get leaders will  not  work.   This  is
           correct behaviour: \a is an uninterpreted leader.  To get leaders use a
           real leader, either by using a control A or like this:
    
                  .ds a \a
                  .TS
                  tab(;);
                  lw(1i) l.
                  A\*a;B
                  .TE
