How can I create simple LATEX document to include exported table ?

You can simply include table in your LATEX documents, minimal sample document should look like following one (assuming you have table exported in file table.tex):

\documentclass{article} % or any class you want
\usepackage{longtable} % for displaying table
\begin{document} % start of document
\include{table} % including exported table
\end{document} % end of document
