These environments produce a box consisting of a sequence of rows of items,aligned vertically in columns. The mandatory and optional arguments consist of:

- `width` Specifies the width of the tabular* environment. There must be rubber space between columns that can stretch to fill out the specified width.

- `pos` Specified the vertical position; default is alignment on the center of the environment.

- t - align on top row

- b - align on bottom row

  - `cols` Specifies the column formatting. It consists of a sequence of the following specifiers, corresponding to the sequence of columns and intercolumn material.

- l - A column of left-aligned items.

- r - A column of right-aligned items.

- c - A column of centered items.

- | - A vertical line the full height and depth of the environment.

- @{text} - This inserts text in every row. An @-expression suppresses the intercolumn space normally inserted between columns; any desired space between the inserted text and the adjacent items must be included in text. An `\extracolsep{wd}` command in an @-expression causes an extra space of width wd to appear to the left of all subsequent columns, until countermanded by another `\extracolsep` command. Unlike ordinary intercolumn space, this extra space is not suppressed by an @-expression. An `\extracolsep` command can be used only in an @-expression in the cols argument.

- p{wd} - Produces a column with each item typeset in a parbox of width wd, as if it were the argument of a `\parbox[t]{wd}` command. However, a `\\` may not appear in the item, except in the following situations: (i) inside an environment like minipage, array, or tabular, (ii) inside an explicit `\parbox,` or (iii) in the scope of a `\centering,` \raggedright, or `\raggedleft` declaration. The latter declarations must appear inside braces or an environment when used in a p-column element.

- *{num}{cols} - Equivalent to num copies of cols, where num is any positive integer and cols is any list of column-specifiers, which may contain another *-expression.
