Il nuovo LaTeX -- \code{array}

`array`

È un'estensione degli environment tabular e array. Le differenze principali sono:

nuove opzioni nel prambolo degli environment (quelle che definiscono le colonne, per intendersi): riportate qui di seguito dalla documentazione originale;
un nuovo parametro: \extrarowheight (ad esempio \extrarowheight=2pt), che specifica di quanto deve essere aumentato lo spazio tra le righe della tabella (utile perchè di solito le linee orizzontali toccano le lettere maiuscole);
è possibile definire nuovi tipi di colonne, ad esempio con allineamento al punto decimale (in questo caso, però, è meglio usare il package dcolumn ).

Per maggiori dettagli si rimanda alla documentazione originale: A new implementation of LaTeX's tabular and array environment (array.pdf o array.ps.gz).

Unchanged options

l Left adjusted column.

c Centered adjusted column.

r Right adjusted column.

p{width} Equivalent to \parbox[t]{width}.

@{decl} Suppresses inter-column space and inserts decl instead.

New options

m{width} Defines a column of width width. Every entry will be centered in proportion to the rest of the line. It is somewhat like \parbox{width}.

b{width} Coincides with \parbox[b]{width}.

>{cmd} Can be used before an l, r, c, p, m or a b option. It inserts cmd directly in front of the entry of the column.

<{cmd} Can be used after an l, r, c, p{...}, m{...} or a b{...} option. It inserts cmd right after the entry of the column.

| Inserts a vertical line. The distance between two columns will be enlarged by the width of the line in contrast to the original definition of LaTeX.

!{cmd} Can be used anywhere and corresponds with the | option. The difference is that cmd is inserted instead of a vertical line, so this option doesn't suppress the normally inserted space between columns in contrast to @{...}.
