Both the native Org-mode
tables (see Tables) and tables
formatted with the table.el package will be exported properly.
For Org-mode tables, the lines before the first horizontal
separator line will become table header lines. You can use the
following lines somewhere before the table to assign a caption
and a label for cross references, and in the text you can refer
to the object with \ref{tab:basic-data}:
#+CAPTION: This is the caption for the next table (or link)
#+LABEL: tbl:basic-data
| ... | ...|
|-----|----|
Some backends
(HTML, LaTeX, and DocBook) allow you to directly include images
into the exported document. Org does this, if a link to an image
files does not have a description part, for example
[[./img/a.jpg]]. If you wish to define a caption for
the image and maybe a label for internal cross references, make
sure that the link is on a line by itself and precede it with
#+CAPTION and #+LABEL as follows:
#+CAPTION: This is the caption for the next figure link (or table)
#+LABEL: fig:SED-HR4049
[[./img/a.jpg]]
You may also define additional attributes for the figure. As this is backend-specific, see the sections about the individual backends for more information.
