-- A TableTooltip is a tooltip designed for formatted text that doesn't wrap,
-- especially for displaying data in columns or in-line textures that want
-- vertically-centered fontstrings. Use RematchTooltip for traditional tooltips
-- with wrapping lines of text.
-- data is an ordered table with each entry as a line; a line can be either a
-- string or a sub-table that will display in separate columns:
-- ex: {"This is the title", {"Wins:",wins},	{"Losses:",losses} }
-- layout is an optional unordered table to define extra details
-- ex: {height=16, justifyH={"LEFT","RIGHT"},colors={nil,{1,1,1}}}
