Text not vertically aligned within tabular with nested tabular

I am trying to vertically align a row heading with a table inside the row. But no matter what I do, the heading remains in the center. I tried using p{'width'}, but that had no change.

\documentclass{article}

\begin{document}

\begin{tabular}{@{}l l}
\Large{Row Heading 1} & Some text that can span the entire page. \vspace{6pt} \\
\Large{Row Heading 2} & \begin{tabular}{@{}l l}
\small{Column data} & \hspace{1in} \small{Column data} \\
\small{Column data} & \hspace{1in} \small{Column data} \\
\\
\small{Column data} & \hspace{1in} \small{Column data} \\
\small{Column data} & \hspace{1in} \small{Column data} \\
\end{tabular}
\end{tabular}

\end{document}


• Welcome to TeX.SX. On this site, questions should include a "Minimal Working Example" (MWE) that starts with \documentclass, includes all relevant \usepackage commands, ends with \end{document} and compiles without errors, even if it does not produce your desired output. – Sandy G Mar 1 at 3:12
• @SandyG I edited my question so the code was a MWE. – Jacob Bischoff Mar 1 at 3:41

If your objective is to align "Row Heading 2" with the top row of the "inner" tabular environment, you should change the setup of the inner tabular from

\begin{tabular}{@{}l l}


to

\begin{tabular}[t]{@{}l l}  % [t] for "top alignment".


Here's a cleaned-up version of your example code. Note that \Large and \small are switches, i.e., they don't take arguments. I've also replaced \vspace{6pt} \\ with the more idiomatic expression \\[6pt], and I've gotten rid of the six \hspace{1in} directives by making the inter-column spacing a part of the definition of the inner tabular environment.

\documentclass{article}
\usepackage{tabularx} % for 'tabularx' environment
\begin{document}

\noindent
\begin{tabularx}{\textwidth}{@{}l X@{}}
\Large Row Heading 1 & Some text that can span the entire page. \\[6pt]
