+ table format . + data + ... + \&.TE +.Ed +.Pp +Each table is formatted independently, and thus must contain a full +separate specification. +The +.Sq table options +affect the entire table. +Alternately, the +.Sq table format +can be changed in the middle of a table, +which yields the following template: +.Bd -literal + \&.TS + table options ; + table format . + table data + \&... + \&.T& + table format . + more data + \&... + \&.TE +.Ed +.Pp +.Ss TABLE OPTIONS +Options affecting the whole table may appear on a single line, +immediately following the +.Sq .TS +line. +The option names may be separated by spaces, tabulations, or commas, +and must end in a semicolon. +Available options are: +.Bl -tag -width linesize(n) +.It allbox +put a box around each item in the table. +.It box +put a box around the whole table. +.It center +center the table, instead of the default left-adjust. +.It delim(ab) +use +.Ar a +and +.Ar b +as +.Xr eqn 1 +delimiters. +.It doublebox +put a double box around the whole table. +.It expand +make the table as wide as the current line length. +.It linesize(n) +set lines and rules in +.Ar n +point type. +.It tab(n) +use +.Ar n +spaces instead of a tabulation to separate items. +.El +.Ss TABLE FORMAT +Each line in the format section corresponds to a single line of the table, +except for the last line which corresponds to all remaining lines up to the +next +.Sq .T& , +if present. +Each column is represented by one letter from the following list, along +with modifiers. +Good style mandates separating specifications for each column with spaces +or tabs. +.Bl -tag -width l or L +.It l or L +left-adjusted column entry. +.It c or C +centered column entry. +.It r or R +right-adjusted colum entry. +.It n or N +numerical column entry, to be aligned with other numerical entries so that +unit digits match up. +.It a or A +alphabetic subcolumn. +Corresponding entries are left-aligned, and set so that the widest is centered +within the column. +.It s or S +spanned heading. +.It ^ +vertically spanned heading. +.El +.Ss TABLE DATA +.Sh GNU DIFFERENCES +The version of +.Nm +shipping with +.Ox +is part of +.Xr groff 1 , +and features a few differences from classical +.Ux +.Nm . +.Pp +For instance, the output of GNU +.Nm +cannot be processed with +.Ux +.Xr troff 1 , +but must be processed with GNU +.Xr troff 1 . +.Pp +Normally, +.Nm +makes use of diversions to attempt to prevent bad breaks in the table. +This can interact with some macro packages' use of diversions, for instance +with footnotes. +The +.Ar nokeep +option +can be used to tell +.Nm +not to try. +.Pp +The +.Ar decimalpoint (c) +option changes the character used as a decimal point instead of the default +period. +.Pp +The +.Ar f +format modifier can be used with a long font name enclosed in parenthesis. +.Pp +A +.Ar d +format modifier has been added, meaning that a vertically spanning entry +should be aligned at the bottom. +.Pp +There are no arrbitrary limits on the number of columns or the number of +text blocks in a table. +.Sh SEE ALSO +.Xr eqn 1 , +.Xr nroff 1 + |
