I am using overleaf environment to create a A0 size poster. The class used for this purpose is 'baposter'. I am trying to use exact table which I had used for the paper submission. However, it is giving errors in poster environment.

\headerbox{Experimental Results}{name=results,span=2,column=1,above=future} {
\begin{table}[t]
\caption{Inference on IR images using WaSR}
\label{wasr_as_is_ir}
    \centering
    \setlength{\tabcolsep}{0.5\dp\strutbox} % the devious trick!
    \begin{tabular}{@{} l @{\quad} ccc @{}}

    \end{tabular}
\end{table}
}

And I am getting these errors -

LaTeX Error: Not in outer par mode.
Undefined control sequence.
\caption@ORI@xfloat ... \global \setbox \@currbox
\color@vbox \normalcolor \...
l.159 }
The control sequence at the end of the top line
of your error message was never \def'ed. If you have
misspelled it (e.g., `\hobx'), type `I' and the correct
spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.
Missing number, treated as zero.

<to be read again>
\vbox
l.159 }

A number should have been here; I inserted `0'.
(If you can't figure out why I needed to see a number,
look up `weird error' in the index to The TeXbook.)

All the errors belong to the last closing curly brace.

This produces a box with the correct title but my beautiful table containing images is missing. What am I missing?

I had posted this question on latex forum and though folks are sincere in their attempt to provide me a solution, it is at best a work around (https://latex.org/forum/viewtopic.php?f=45&t=34274). If the table can be supported inside header box, that will be really great.

Note that the layout of this table was suggested by folks from this forum (when I was working on paper) so I am hopeful that we can find a solution to my problem, this time for the poster.

What's happening here is that you're trying to put a float (table) inside the argument to \headerbox which puts its contents inside a minipage.

A frequent point of confusion is to think that a tabular environment needs to be inside a table environment, but the latter environment is about positioning within the document and otherwise has nothing to do with tables (other than how captions are labeled). You do not need table around your tabular.

The simplest approach for what you want is to just remove the table environment entirely and use the \captionof command to format the caption.

  • Thank you very much. It worked. However, I have a follow-up question which I will have to ask as a separate question because of attachment.
