The trouble is that the default option says "width=.9\\linewidth" so
if you try to put two of them on the same "line", they end up overflowing
the page. For an image not inside a table, you could reset that with

#+ATTR_LaTeX: width=.4\\linewidth

but this is a rather blunt instrument: for images inside a table, it
applies not only to the images but also to the table (and it ends up
producing a syntactically incorrect latex program - that's probably
a bug in the latex exporter.)

The following variation does work however:

--8<---------------cut here---------------start------------->8---
#+BIND: org-export-latex-image-default-option "width=.4\\linewidth"

* foo

| col1         | col2         |
| [[./x1.jpg]] | [[./x2.jpg]] |
|              |              |
--8<---------------cut here---------------end--------------->8---

Of course, if you try to put three images on the line, you'll have to
recalibrate the factor (you can also use absolute dimensions: width=3cm).

There is also this second variation, which uses height, rather than width: the
latex exporter thinks height is not relevant to tables, so it does not
try to give that attribute to the table, just to the images:

--8<---------------cut here---------------start------------->8---
* foo

#+ATTR_LaTeX: height=2cm

| col1         | col2         |
| [[./x1.jpg]] | [[./x2.jpg]] |
|              |              |
--8<---------------cut here---------------end--------------->8---

but you can also use the BIND form too:

#+BIND: org-export-latex-image-default-option "height=2cm"

Note btw, that the width in the first case (and the height in the
second case) is the same for both images. AFAICT, there is no way
to give different dimensions to the two images - except for the
following variation.

The third variation allows the two images to have their "natural"

--8<---------------cut here---------------start------------->8---
#+BIND: org-export-latex-image-default-option ""

* foo

| col1         | col2         |
| [[./x1.jpg]] | [[./x2.jpg]] |
|              |              |
--8<---------------cut here---------------end--------------->8---
