Changing the font size in a table

Question

What's the recommend way of changing the font size in a particular table? Is there a better way than enclosing all values with, for example, the tiny function.

Scale down your table to the textwidth

documentclass{article}
usepackage{graphicx}
begin{document}

begin{table}
resizebox{textwidth}{!}{%
  begin{tabular}{cc}
    Knuth & Lamport
  end{tabular}}
end{table}

end{document}

then you have the optimal font size. However, all tabular lines are also scaled down which doesn't matter because it looks nicer.

Write tiny immediately after begin{table}. If you don't use a (floating) table environment, enclose your (e.g.) tabular environment in a group and write tiny after begingroup.

documentclass{article}

begin{document}

begin{table}
tiny
centering
begin{tabular}{cc}
Knuth & Lamport
end{tabular}
end{table}

end{document}

EDIT: To change the fontsize for all tables (or even floats of every type), one may use the floatrow package (this also saves typing centering in every table):

documentclass{article}

usepackage{floatrow}
DeclareFloatFont{tiny}{tiny}% "scriptsize" is defined by floatrow, "tiny" not
floatsetup[table]{font=tiny}

begin{document}

begin{table}
begin{tabular}{cc}
Knuth & Lamport
end{tabular}
end{table}

end{document}

An easier way to change the font size for ALL tables:
usepackage{etoolbox}
AtBeginEnvironment{tabular}{tiny}
