There are three new parameters: +% +% \tablinesep (or \tablelineskip): minimum space between text on successive +% lines in a tabular environment. Negative distances are +% treated as zero. The default value is 1pt. 0pt turns off +% checking for touching text. Text given in an @{ } +% specification is never checked for overlap. +% +% \arraylinesep (or \arraylineskip): like \tablinesep, but for arrays. +% +% \extrarulesep : extra space to add above and below each \hline and \cline. +% There will be at least \extrarulesep + 0.5\tablinesep +% between an \hline and a line of text. Negative values can +% be used, but only until some text touches the line. +% The default value is 3pt. +% +% To ensure interline separations in tables but not arrays, declare +% \setlength\arraylinesep{0pt} +% The appearance of normal LaTeX tables can be had with +% \setlength\tablinesep{0pt} +% \setlength\arraylinesep{0pt} +% \setlength\extrarulesep{0pt} +% but it would be better to not use tabls in this situation. +% +% \hline[dimen]: +% +% \hline has been changed to take an optional length argument just like \\ +% giving the space to insert below. This space is in addition to the +% \extrarulesep and linesep. A negative value will reduce the space until +% the hline touches some text below, and then will have no further effect. +% E.g., \hline[-9in] draws a horizontal line while suppressing the extrarulesep +% beneath. Also, the new \hline FIXES THE NOTCHES that used to appear at the +% junction between horizontal and vertical lines. +% +% How it works: +% There are no struts in the preamble entries (lie), rather, there are +% tests to measure the maximum height and depth of all entries on a line. +% The maximum values start at the size of LaTeX's \@arstrut minus the +% appropriate linesep. At the \\, a strut is inserted (in its own +% column) which is that maximum size plus the linesep plus any additional +% space for separation from \hline s. +% +% The Downside: +% Building a table will be slower than before because the entries have to +% be boxed twice (by \@seesize and by \halign itself) instead of just once. +% \setlength\tablinesep{0pt} will recover most of this speed, with +% \extrarulesep still partially in effect--extra space will still be added +% around hlines, but it may be taken up by very tall or very deep table +% entries; thus text may still touch the lines. Because of the speed penalty, +% if your computer is slow, it is probably best to omit the TABLS option +% until producing a final copy. +% +% (2.2) \endtabular* is defined (it was left out before. oops!) +% change some \z@ to \z@skip. Thanks to Michael Downes. +% Create alias \tablinesep = \tablelineskip for consistency with +% \tabcolsep nomenclature. \def\\{\crcr} used in ver 2.1 didn't work right, +% so use \csname crcr\endcsname. +% +% (3.0) Arrays are included! The very top and bottom struts of nested +% arrays are reduced by the lesser of the inner and outer lineseps so space +% doesn't accumulate with each level of nesting. +% +% (3.1 & 3.2 & 3.3) Minor changes to match LaTeX updates. +% +% (3.4) More extensive changes, prompted by LaTeX updates. You can now hide +% \hline in another macro, and it is still recognized. [Similar commands that +% add \extrarulesep must begin with \noalign.] \hline[3pt]\hline is now +% reasonable. (Also try \hline[0pt]\hline!) +% +% (3.5) Fix several (non-crashing) bugs introduced in 3.4 +% +% Send problem reports to asnd@Reg.TRIUMF.CA +% +% Test integrity of file: +% brackets: round, square, curly, angle: () [] {} <> +% backslash, slash, vertical, at, dollar, and: \ / | @ $ & +% hat, grave, acute (apostrophe), quote, tilde: ^ ` ' " ~ |
