I have a table that is very slightly to wide for the page. It contains table notes \tnote{} and these are what made my table too wide. Now I recall from the documentation of one of several packages that go together to make complicated tables work that one of the authors put in a switch to enable indices to be pushed into the inter-column spacing. I'm aware that I can manually put in !{} and @{} type specifiers to try and sort things out but I thought that there was something automatic that did it. I am using these packages that relate to tables: siunitx, dcolumn, array, threeparttable, multirow, longtable, booktabs and have tried and failed to find the option in the documentation.

Can any one remember what the command is?, probably something that goes in the table preamble.


Edit: here is an example (the doc preamble is a bit of a mouthful, I'm afraid i just copied and pasted this.):

\usepackage[output-complex-root=\text{\ensuremath{i}}  % Says that I want italic maths i to signify imaginary components.
            ,load-configurations=abbreviations         % Enables many abbreviations like \eV, however this has separate scope to doc wide macros.
            ,detect-weight                             % Detect the weighting (bold) of surrounding text.
            ,range-units=single                        % Can specify a range like 1 to 2eV or 1eV to 2eV. \SIrange{1}{2}{\eV}
            ,list-units=single                         % Same as range-units only for list. \SIlist{1;2;3;4}{\eV}
            ,table-alignment=center                    % Sets -number- -text- -unit- alignment to center unless superceeded in \sisetup{}. 
                                                       % If not set, then numbers centered on radix. if set, must specify format for correct placement
            ,group-digits=false                        % separates digits into blocks of three (can change other settings to make it comma separated.
            ]{siunitx} % for proper typesetting of units, still under development as best as i can tell... I'm scared \si{} \SI{}{}


        \begin{tabular}{c c c c}
           things              & more things              & bumbily boo              & Numbers \\
           1.23412435\tnote{a} & 123543124513452\tnote{b} & dogCatWolfSheep\tnote{c} & -2.1214153124\tnote{d} \\

Can you please add to your question a minimal working example showing a reduced version of your actual table? – Gonzalo Medina May 31 '11 at 20:43

In generating the example above I realized that the \tnote command was part of the three part table package. The command I wanted is \TPTrlap to be placed in the optional argument of the threeparttable environment. From the manual: A command with one argument, to make notes go out of the column, into the column separation (for right-aligning).

Further to this answer. I find that threeparttable pushes the \tnote{} to the intercolumn spacing by default and will do this in the case of a siunitx S column as well. One simply needs to make no mention of the size of the table note in the table-align-text-post={a} argument which adds space for non numerical data. It will allow the notes to creep into the intercolumn spacing without producing hbox overful errors.
