Unwanted space at bottom of tabularx cell

While trying to solve another issue of mine, I encountered the following issue:

In a tabularx cell there is unwanted space getting inserted at the bottom when using the following code:

documentclass[border=1cm]{standalone}

usepackage{tikz}
usepackage{tabularx}

renewcommand{tabcolsep}{0mm}
tikzset{inner sep=0mm}

begin{document}
begin{tabularx}{10cm}{|X|X|}
    hline
    rule{2cm}{2cm} & rule{2cm}{2cm} 
    hline
    tikz{node[fill,minimum width=2cm,minimum height=2cm]{};} & tikz{node[fill,minimum width=2cm,minimum height=2cm]{};} 
    hline
    Also get it & with text 
    hline
end{tabularx}
end{document}

Picture:

I suppose that space is for the stuff that belongs below the baseline of a text. Since I only want to put tikzpictures into the cells, how can I disable this behaviour?

Thanks in advance!
