    [ZEPPELIN-771] Escape tab and CR when the result is shown in table

    ### What is this PR for?
    
    The presence of the characters `\t` and `'n` in the data to be displayed 
can cause the failure of successfully displaying a table. Indeed, these two 
characters are used as separators in a table. Some interpreters, don't escape 
the data to be shown.
    This PR address the issue replacing the characters as previosly done for 
some of the interpreters like geode.
