I've come across this odd problem where the words in the final cell of my final column don't want to align themselves to the middle of that particular cell. This is my LaTeX code:
\documentclass{article}
\usepackage{tabu}
\usepackage{hyperref}
\begin{document}
\setcounter{footnote}{2} % mimic actual document
\begin{table}
\centering
\begin{tabu} to 0.95\textwidth {|X[2,c,m]|X[1,c,m]|X[1,c,m]|X[1,c,m]|}
\hline Proposed syllabification & Sonority Ranking Hierarchy & Maximum Onset Principle\footnotemark & Morpheme Boundaries \\[9pt]
\hline\hline
\end{tabu}
\end{table}
\end{document}
And this is how it looks:
Could anyone suggest a solution?
