Here is another approach. What it does is to check at the end of the document the values of the figure
and table
counters, and add to the .aux
file a boolean flag setting depending on whether these values are zero or positive.
Then you have on next run \iffigures
and \iftables
which allow you to act conditionally.
In the code below, perhaps the \global
are not really needed, I didn't check.
See also a variant at bottom which does not use the figure
/table
counters because they might well be reset to zero due to document sectioning (as pointed out by egreg
in a comment).

Here is for a document with figures but no tables:
And if tables are present:
Three compilations needed.
Variant. I don't know to what extent patching \figure
and \table
as here is OK, depends perhaps on float related packages. At the worst I guess doing the patches immediately after \begin{document}
should be enough (at the end of preamble might not be enough if some package does stuff during At Begin Document).

Package tocbibind
includes LoF and LoT unnumbered in ToC. The list of figures gets numbered if you redefine \listoffigures
using command \tocsection
. So you only have to remove this redefinition of \listoffigures
to get an unnumbered LoF including a ToC entry.

You can use the
chngcntr
package to change the counter for figures and the one for the tables, and thetocloft
package to add the words "Table" and "Figure" to the list of tables and figures. A little example:Only the combined list of the resulting document is shown:
