53it must be processed with GNU 54.BR troff . 55If no files are given on the command line, the standard input 56will be read. 57A filename of 58.B \- 59will cause the standard input to be read. 60. 61. 62.SH OPTIONS 63.TP 64.B \-C 65Recognize 66.B .TS 67and 68.B .TE 69even when followed by a character other than space or newline. 70.TP 71.B \-v 72Print the version number. 73. 74. 75.SH USAGE 76.B tbl 77expects to find table descriptions wrapped in the 78.B .TS 79(table start) and 80.B .TE 81(table end) macros. 82The line immediately following the 83.B .TS 84macro may contain any of the following global options (ignoring the case 85of characters -- Unix tbl only accepts options with all characters lowercase 86or all characters uppercase): 87. 88.TP 89.B center 90Centers the table (default is left-justified). 91The alternative keyword name 92.B centre 93is also recognized (this is a GNU tbl extension). 94. 95.TP 96.BI delim( xy ) 97Use 98.I x 99and 100.I y 101as start and end delimiters for 102.BR @g@eqn (@MAN1EXT@). 103. 104.TP 105.B expand 106Makes the table as wide as the current line length. 107. 108.TP 109.B box 110Encloses the table in a box. 111. 112.TP 113.B doublebox 114Encloses the table in a double box. 115. 116.TP 117.B allbox 118Encloses each item of the table in a box. 119. 120.TP 121.B frame 122Same as box (GNU tbl only). 123. 124.TP 125.B doubleframe 126Same as doublebox (GNU tbl only). 127. 128.TP 129.BI tab( x ) 130Uses the character 131.I x 132instead of a tab to separate items in a line of input data. 133. 134.TP 135.BI linesize( n ) 136Sets lines or rules (e.g. from 137.BR box ) 138in 139.IR n -point 140type. 141. 142.TP 143.B nokeep 144Don't use diversions to prevent page breaks (GNU tbl only). 145Normally 146.B tbl 147attempts to prevent undesirable breaks in the table by using diversions. 148This can sometimes interact badly with macro packages' own use of 149diversions, when footnotes, for example, are used. 150. 151.TP 152.BI decimalpoint( c ) 153Set the character to be recognized as the decimal point in numeric 154columns (GNU tbl only). 155. 156.TP 157.B nospaces 158Ignore leading and trailing spaces in data items (GNU tbl only). 159. 160.LP 161The global options must end with a semicolon. 162There might be whitespace after an option and its argument in parentheses. 163.LP 164After global options come lines describing the format of each line of 165the table. 166Each such format line describes one line of the table itself, except that 167the last format line (which you must end with a period) describes all 168remaining lines of the table. 169A single key character describes each column of each line of the table. 170You may run format specs for multiple lines together on the same line by 171separating them with commas. 172.LP 173You may follow each key character with specifiers that determine the font 174and point size of the corresponding item, that determine column width, 175inter-column spacing, etc. 176.LP 177The longest format line defines the number of columns in the table; missing 178format descriptors at the end of format lines are assumed to be `L'. 179Extra columns in the data (which have no corresponding format entry) are 180ignored. 181.LP 182The available key characters are: 183. 184.TP 185c,C 186Centers item within the column. 187. 188.TP 189r,R 190Right-justifies item within the column. 191. 192.TP 193l,L 194Left-justifies item within the column. 195. 196.TP 197n,N 198Numerically justifies item in the column: Units positions of numbers are 199aligned vertically. 200. 201.TP 202s,S 203Spans previous item on the left into this column. 204. 205.TP 206a,A 207Centers longest line in this column and then left-justifies all other lines 208in this column with respect to that centered line. 209. 210.TP 211^ 212Spans down entry from previous row in this column. 213. 214.TP 215_,- 216Replaces this entry with a horizontal line. 217. 218.TP 219= 220. 221Replaces this entry with a double horizontal line. 222. 223.TP 224| 225The corresponding column becomes a vertical rule (if two of these are 226adjacent, a double vertical rule). 227. 228.LP 229A vertical bar to the left of the first key-letter or to the right of the 230last one produces a line at the edge of the table. 231.LP 232Here are the specifiers that can appear in suffixes to column key letters: 233. 234.TP 235b,B 236Short form of fB (make affected entries bold). 237. 238.TP 239i,I 240Short form of fI (make affected entries italic). 241. 242.TP 243t,T 244Start an item vertically spanning rows at the top of its range rather than 245vertically centering it. 246. 247.TP 248d,D 249Start an item vertically spanning rows at the bottom of its range rather 250than vertically centering it (GNU tbl only). 251. 252.TP 253v,V 254Followed by a number, this indicates the vertical line spacing to be used in 255a multi-line table entry. 256If signed, the current vertical line spacing is incremented or decremented 257(using a signed number instead of a signed digit is a GNU tbl extension). 258A vertical line spacing specifier followed by a column separation number 259must be separated by one or more blanks. 260No effect if the corresponding table entry isn't a text block. 261. 262.TP 263f,F 264Either of these specifiers may be followed by a font name (either one or two 265characters long), font number (a single digit), or long name in parentheses 266(the last form is a GNU tbl extension). 267A one-letter font name must be separated by one or more blanks from whatever 268follows. 269. 270.TP 271p,P 272Followed by a number, this does a point size change for the affected fields. 273If signed, the current point size is incremented or decremented (using a 274signed number instead of a signed digit is a GNU tbl extension). 275A point size specifier followed by a column separation number must be 276separated by one or more blanks. 277. 278.TP 279w,W 280Minimal column width value. 281Must be followed either by a 282.BR @g@troff (@MAN1EXT@) 283width expression in parentheses or a unitless integer. 284If no unit is given, en units are used. 285Also used as the default line length for included text blocks. 286If used multiple times to specify the width for a particular column, 287the last entry takes effect. 288. 289.TP 290e,E 291Make equally-spaced columns. 292. 293.TP 294u,U 295Move the corresponding column up one half-line. 296. 297.TP 298z,Z 299Ignore the corresponding column for width-calculation purposes. 300. 301.LP 302A number suffix on a key character is interpreted as a column 303separation in ens (multiplied in proportion if the 304.B expand 305option is on). 306Default separation is 3n. 307.LP 308The format lines are followed by lines containing the actual data for the 309table, followed finally by 310.BR .TE . 311Within such data lines, items are normally separated by tab characters (or 312the character specified with the 313.B tab 314option). 315Long input lines can be broken across multiple lines if the last character 316on the line is `\e' (which vanishes after concatenation). 317.LP 318A dot starting a line, followed by anything but a digit is handled as a 319troff command, passed through without changes. 320The table position is unchanged in this case. 321.LP 322If a data line consists of only `_' or `=', a single or double line, 323respectively, is drawn across the table at that point; if a single item in a 324data line consists of only `_' or `=', then that item is replaced by a 325single or double line, joining its neighbours. 326If a data item consists only of `\e_' or `\e=', a single or double line, 327respectively, is drawn across the field at that point which does not join 328its neighbours. 329.LP 330A data item consisting only of `\eRx' (`x' any character) is replaced by 331repetitions of character `x' as wide as the column (not joining its 332neighbours). 333.LP 334A data item consisting only of `\e^' indicates that the field immediately 335above spans downward over this row. 336.LP 337A text block can be used to enter data as a single entry which would be 338too long as a simple string between tabs. 339It is started with `T{' and closed with `T}'. 340The former must end a line, and the latter must start a line, probably 341followed by other data columns (separated with tabs). 342.LP 343To change the data format within a table, use the 344.B .T& 345command (at the start of a line). 346It is followed by format and data lines (but no global options) similar to 347the 348.B .TS 349request. 350. 351. 352.SH "INTERACTION WITH @G@EQN" 353.BR @g@tbl (@MAN1EXT@) 354should always be called before 355.BR @g@eqn (@MAN1EXT@) 356.RB ( groff (@MAN1EXT@) 357automatically takes care of the correct order of preprocessors). 358. 359. 360.SH "GNU TBL ENHANCEMENTS" 361There is no limit on the number of columns in a table, nor any limit on the 362number of text blocks. 363All the lines of a table are considered in deciding column widths, not just 364the first 200. 365Table continuation 366.RB ( .T& ) 367lines are not restricted to the first 200 lines. 368.LP 369Numeric and alphabetic items may appear in the same column. 370.LP 371Numeric and alphabetic items may span horizontally. 372.LP 373.B @g@tbl 374uses register, string, macro and diversion names beginning with the digit\~\c 375.BR 3 . 376When using 377.B @g@tbl 378you should avoid using any names beginning with a\~\c 379.BR 3 . 380. 381. 382.SH BUGS 383You should use 384.BR .TS\ H / .TH 385in conjunction with a supporting macro package for 386.I all 387multi-page boxed tables. 388If there is no header that you wish to appear at the top of each page 389of the table, place the 390.B .TH 391line immediately after the format section. 392Do not enclose a multi-page table within keep/release macros, 393or divert it in any other way. 394.LP 395A text block within a table must be able to fit on one page. 396.LP 397The 398.B bp 399request cannot be used to force a page-break in a multi-page table. 400Instead, define 401.B BP 402as follows 403.IP 404.B .de BP 405.br 406.B .ie '\e\en(.z'' .bp \e\e$1 407.br 408.B .el \e!.BP \e\e$1 409.br 410.B .. 411.br 412.LP 413and use 414.B BP 415instead of 416.BR bp . 417.LP 418Using \ea directly in a table to get leaders will not work. 419This is correct behaviour: \ea is an 420.B uninterpreted 421leader. 422To get leaders use a real leader, either by using a control A or like 423this: 424.IP 425.nf 426.ft B 427\&.ds a \ea 428\&.TS 429tab(;);
