How could I add before title the source of the table? Also, in the first row how could I center between 2010 and provisional the other dates?
\begin{table}[ht]
\centering % used for centering table
\begin{tabular}{l c c c c c c}
\hline %inserts double horizontal lines
& 1990 & 1999 & 2005 & 2010 & 2015 \\
& & & & (provisional) & (projection)\\
\hline% inserts single horizontal line
East Asia \& Pacific & 48.5 & 37.6 & 23.9 & 20.7 & 11.8 \\
Europe \& Central Asia & 0.5 & 1.0 & 0.5 & 0.3 & 0.2 \\
Latin America \& Caribbean & 2.8 & 3.4 & 3.4 & 2.7 & 3.1 \\
Middle East \& North Africa & 0.7 & 0.8 & 0.8 & 0.7 & 1.0 \\
South Asia & 32.3 & 35.5 & 43.1 & 41.7 & 41.9 \\
Sub-Saharan Africa & 15.2 & 21.6 & 28.4 & 34.1 & 42.1 \\ [1ex] % [1ex] adds vertical space
\hline \hline
\end{tabular}

\end{table}
Best Answer
For the source, I just add an extra (footnotesize) line to the end of the table. To center the headers vertically, I used the
\stackanchor
macro from thestackengine
package. The\addstackgap
pads the stack with a little extra space above and below.
