THREE FOURone The width ofthis column isfixed (5.5pc).three Column fourwill act in thesame way ascolumn two,with the samewidth.The following examples use virtually the same contents, the major differences are thespecifications of the environment.Note that the horizontal rules extend beyond the last column. There are no X columnsand the total width required to set the tabular* is less than the 250pt specified for thewidth.Compare the previous narrow tabular* with the next one which is set with\begin{tabular*}{300pt}%{|@{\extracolsep{\fill}}c|p{5.5pc}|c|p{5.5pc}|}The main differences between the tabularx and tabular* environments are:• tabularx modifies the widths of the columns, whereas tabular* modifies thewidths of the intercolumn spaces.• tabular and tabular* environments may be nested with no restriction, howeverif one tabularx environment occurs inside another, then the inner one must be enclosedby { }.• The body of the tabularx environment is in fact the argument to a command, andso certain constructions which are not allowed in command arguments (like \verb)222
