This page deals with tips related to "uber-huge" tables in
psuthesis. Anyway, by "uber-huge" I mean tables that
either: 1. cover multiple pages, or 2. cover multiple pages *and* need
to be presented landscape.
Courtesy of Ann Hornschemeier we have a style file that allows the use
of
AAS deluxetables
with the psuthesis format, and this works really
well, with one exception: uber-huge tables. It doesn't really doesn't
work too well because AASTeX is too clever for its own good - it does
not allow you to specify a "table of contents" entry with a
deluxetable. So, what happens is LaTeX then takes the title of the
deluxetable and adds an individual entry into the table of contents
for *each page* that the uber-huge table falls on (which makes for
unnecessary clutter).
So, I happened across a fix (google is a wonderful thing), which does
not require too much modification from the deluxetable format and is
much more friendly to the table of contents by adding only a single
entry (but you only need to worry about this if you have tables that
span multiple pages, deluxetable works fine for single-page tables -
oh, and you can use this *in addition* to deluxetable).
The fix is to use "longtable" instead of
"deluxetable". To do this, you need to add a
"\usepackage{longtable}" into the document preamble.
\begin{center}
\begin{longtable}{lll}
%Here is the caption, the stuff in [] is the table of contents entry,
%the stuff in {} is the title that will appear on the first page of the
%table.
\caption[Feasible triples for a highly variable Grid]{Feasible triples
for highly variable Grid, MLMMH.} \label{grid_mlmmh} \\
%This is the header for the first page of the table...
\hline \hline \\[-2ex]
\multicolumn{1}{c}{\textbf{Time (s)}} &
\multicolumn{1}{c}{\textbf{Triple chosen}} &
\multicolumn{1}{c}{\textbf{Other feasible triples}} \\[0.5ex] \hline
\\[-1.8ex]
\endfirsthead
%This is the header for the remaining page(s) of the table...
\multicolumn{3}{c}{{\tablename} \thetable{} -- Continued} \\[0.5ex]
\hline \hline \\[-2ex]
\multicolumn{1}{c}{\textbf{Time (s)}} &
\multicolumn{1}{c}{\textbf{Triple chosen}} &
\multicolumn{1}{c}{\textbf{Other feasible triples}} \\[0.5ex] \hline
\\[-1.8ex]
\endhead
%This is the footer for all pages except the last page of the table...
\multicolumn{3}{l}{{Continued on Next Page\ldots}} \\
\endfoot
%This is the footer for the last page of the table...
\\[-1.8ex] \hline \hline
\endlastfoot
%Now the data...
0 & (1, 11, 13725) & (1, 12, 10980), (1, 13, 8235), (2, 2, 0), (3, 1, 0) \\
2745 & (1, 12, 10980) & (1, 13, 8235), (2, 2, 0), (2, 3, 0), (3, 1, 0) \\
5490 & (1, 12, 13725) & (2, 2, 2745), (2, 3, 0), (3, 1, 0) \\
8235 & (1, 12, 16470) & (1, 13, 13725), (2, 2, 2745), (2, 3, 0), (3, 1, 0) \\
% <data removed>
164700 & (1, 13, 13725) & (2, 2, 2745), (2, 3, 0), (3, 1, 0) \\
\end{longtable}
\end{center}
Anyway, the biggest differences from a deluxetable are in the headers
(you specify headers for the first page, then for each subsequent page
separately), and the footers (you can specify a footer for the last
page and all other pages).
The longtable example above will produce a multi-page,
portrait-oriented table. If you want to make the table oriented
landscape, all you need to do is replace the
"\begin{center}" and "\end{center}" with
"\begin{landscape}" and "\end{landscape}" then add
"\usepackage{lscape}" in the preamble (or just add it to:
"\usepackage{longtable,lscape}").
Also note that the headers are entered as
\multicolumn{1}{c}{\textbf{Header}} - this produces a column
header that is centered over the column and in bold-face (like AAS
deluxetables). You do not need to use multicolumn, but then the header
for the column will be aligned following the column alignments given in
\bedin{longtable}{lll}. It is perfectly OK to have headers spaning
multiple columns. Also, your header row can have multiple lines, after you've
written the first line of headers, add a "\\" to start a new line
then add the second row of headers. For example:
%This is the header for the first page of the table...
\hline \hline \\[-2ex]
% First row of headers
\multicolumn{1}{c}{\textbf{Object Name}} &
\multicolumn{2}{c}{\textbf{V Magnitude}} & % Header spans two columns
\multicolumn{1}{c}{\textbf{Note}} \\
% Second row of headers
\multicolumn{1}{c}{\textbf{~}} & % Blank Header
\multicolumn{1}{c}{\textbf{(mag)}} &
\multicolumn{1}{c}{\textbf{(error)}} &
\multicolumn{1}{c}{\textbf{~}} \\[0.5ex] \hline % Blank Header
\\[-1.8ex]
\endfirsthead
\renewcommand{\thefootnote}{\alph{footnote}}
Then write your table. Enter the "\tablenotemark{}"
commands as you normally would with letters, but enter the
"\footnotetext[]{}" commands using the number corresponding
to the position in the alphabet of the letter you would like as the
footnote (a=1, b=2, c=3, ...). Then after your table enter the
following to reset the footnotes for the rest of the document:
\renewcommand{\thefootnote}{\arabic{footnote}}
Or, if you want to use the 9 "footnote symbols":
Now here is a complicated example of a landscape formated longtable,
with lettered table notes at the end, and script-sized font (again, I
removed some of the data to save space - also the headers are not in
bold face like the earlier example):
\begin{landscape}
% Change the footnote style to lowercase letters
\renewcommand{\thefootnote}{\alph{footnote}}
\scriptsize

To adjust the spacing between lines in your longtable (i.e., to make the table double or 1.5 spaced for some reason in a single space environment, or to make the table single spaced in a double spaced environment), use the command:
\renewcommand{\arraystretch}{x.xx}
where "x.xx" is a line spacing, well, actually it is what
the current line spacing is multiplied by before it is applied to the
table lines (default is "1"; in single space mode, to double
space the table enter "2", for 1.5 spacing enter
"1.5", etc.; in double space mode, to single space a table
enter "0.5", etc.). I have not done extensive testing of this
command, as far as I can tell it will affect all longtables, tabular,
and array environments (but not deluxetables) after it is issued (so
it might be a good idea to reset it back to "1" after the
table if you do not want all tables to have that spacing). You can
either specify this command in the preamble of the document (to affect
the whole thing), or right before you need it (to affect everything
after that point).
The command "\\" which is used to end a line (in a table or a paragraph), has some special "tricks up-its-sleeve" (you may have noticed this in some of the example tables above)...
While entering several longtables in a chapter, I encountered a
problem where LaTeX basically choked on the last longtable. It
continuously said the "table widths have changed, rerun
LaTeX", and the table would be formated really crazy no matter
how many times I ran LaTeX (normally I found it should take only 3-5
times running LaTeX in order to get the columns of a longtable
adjusted appropriately).
The specific circumstances were: I added a new longtable in between
two previously existing longtables (so tables 1 and 3 were
pre-existing and compiled fine before, and table 2 was the new one).
Then, when I compiled the document, LaTeX became unable to format the
very last longtable (table 3 --- one of the previously fine tables).
So, the "fix" I'm talking about here applies to this last
table (the one that was OK, but now with the addition of the new table
before it, won't compile anymore).
This problem totally baffled me for a while, but I finally found a
"fix" that seemed to work (although I will completely admit
that I have absolutely NO idea why this seemed to work). So,
if you encounter the problem where LaTeX can't seem to get a longtable
formated correctly, here is something you can try (it may, or may not,
work for you, and again, I have absolutely NO idea why this worked
for me):
Another thing to try that I thought of as I was moving this webpage, would be to delete all the auxilary files that LaTeX produces (specifically the .aux file associated with the specific chapter input containing the offending table), then recompiling. I haven't actually tried this, so I don't know if it will work, but it might be something to try first before going through all the trouble above.
