In the first version, only one expression is passed to Plot[], not a
list of expressions. For some reason Plot[] does not notice that this
expression is going to evaluate to a list when it chooses the palette.
The solution is to evaluate the expression manually, or ask Plot[] to
evaluate it before substituting any values for x:
Plot[Table[Sin[n x], {n, 3}] // Evaluate, {x, 0, 2 Pi},
PlotStyle -> Thick]
Plot[Table[Sin[n x], {n, 3}], {x, 0, 2 Pi},
PlotStyle -> Thick, Evaluated -> True]
