### 2.6.19: tabular

       \begin{tabular}[pos]{cols}
       column 1 entry & column 2 entry ... & column n entry \\
       .
       .
       .
       \end{tabular}

or

       \begin{tabular*}{width}[pos]{cols}
       column 1 entry & column 2 entry ... & column n entry \\
       .
       .
       .
       \end{tabular*}

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` | Specifies the vertical position; default is alignment on the centre 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 centred 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: inside an environment like `minipage`, `array`, or `tabular`. inside an explicit `\parbox`. 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`.

These commands can be used inside a `tabular` environment:

- \cline Draw a horizontal line spanning some columns.
- \hline Draw a horizontal line spanning all columns.
- \multicolumn Make an item spanning several columns.
- \vline Draw a vertical line.
