<ARRAY> Math Array

Definition:

The <ARRAY> element is used for LaTeX-like arrays (LaTeX is a text-processing environment built around Donald Knuth's TeX typesetting language designed to make it easy to produce technical, notation-rich books and manuscripts).

Attributes:

ALIGN
By default, arrays are vertically positioned so that preceding and following expressions are aligned with the mid point of the array. The ALIGN attribute can take on of the following values:

TOP

The top row of the array is aligned with the same baseline as the preceding or following expression.

MIDDLE

The middle row of the array is aligned with the same baseline as the preceding or following expression. This is the default. If there are an even number of rows, the midpoint of the array is used instead.

BOTTOM

The bottom row of the array is aligned with the same baseline as the preceding or following expression.

COLDEF
By default the columns are centered. This attribute can be used to specify the horizontal alignment for each column with character string formed by one capital letter per column, with L for left, C for center and R to right alignment, e.g. "LLCR" for a 4 column table.
The COLDEF attribute can also be used to place a "+", "-" or "=" between the columns, e.g. coldef="C+C+C+C=C". Whitespace within the COLDEF attribute is ignored.

LDELIM
An entity or character for the left delimiter, e.g. ldelim="[" for a left square bracket or ldelim="|". The default is no delimiter.

RDELIM
An entity name or character for the right delimiter, e.g. rdelim="}" or rdelim="|". The default is no delimiter.

LABELS
The presence of this attribute has the same effect as TeX's bordermatrix command. The first row and column are separated from the rest of the array.

Context:

<ARRAY> is legal within:
<ABOVE>, <BAR>, <BELOW>, <BOX>, <BT>, <DDOT>, <DOT>, <HAT>, <ITEM>, <MATH>, <OF>, <ROOT>, <SQRT>, <T>, <TILDE>, <VEC>

The following markup can be used within <ARRAY>
<ROW>
