pretending to have a table, but placing an image (of an table) in order to get table counting [closed]

Question

I have images of tables (screenshots from Excel actually), and up to now I'm using this structure.

\begin{table}[htp]
\includegraphics{mytable.png}
\caption{\label{tab:MyTable}some description}
\end{table}

As far as I have gathered, this is the way to go if I want to get a numbering like "Table 1.99" - which I want it to be.

My problem is that the space between caption and picture is different with every table. Is that because the table-images are all of different height and it gets rounded to \baselineskip or something similar? The idea would then be to make the table be vertically aligned at the bottom (I would not care about extra space above a table, but between table and caption that looks no good) - which I don't know how to achieve.

BTW:

• I am aware of the fact that it is recommended to place captions above images, but I want it to have the same appearance as my images.
• I also would like to use table because I want my tables to be listed on the list of tables (so changing "Figure" to "Table" but using begin{figure} won't do the trick for me).
• I know that using built-in tables would be better, but that's currently not the way to go
• My images do not have spurious white space at any side

EDIT: In order to have all the text equally sized in all "tables", the screenshots were taken at the same zoom level from Excel. The widest table determined the dpi number which was then set for all the table-images (BTW: 215 dpi), so that it fittet on the page. Might that odd resolution be the problem? I'm trying to reproduce it with other images, but it seems random somehow...

Answer 1

As it turned out - and frankly I don't know the real reasons - it all depends on the physical size of the images. So if the resolution is high enough, the image will fit (horizontally) onto the page and the caption will be placed close to the image. If the resolution is too low, so that the image is too wide, the caption is moved away from the image.

The main problem was in my case, that I had used [width=\textwidth] in some cases (so it was not obvious right away), trusting in LaTeX to make it fit perfectly onto the page taking all the horizontal space possible. Yet in my configuration (don't know what/where the culprit is), this always resulted having extra space between table and caption, no matter high the res was set on the pictures.

I have used the etoolbox package and the \AtBeginEnvironment and \AtEndEnvironment to fine tune spacing, but there's not more to it than \vspace{...} so I don't suspect that to be the problem.

Sorry, for not being able to provide a profound explanation - instead of a work around which may even not apply generally.
