Having some difficulties getting array, and delarray to do what I want. 
For example,

\documentclass[11pt]{article}
\usepackage{delarray}

\begin{document}

$
\begin{array}({cc})
a & b\\
c & d
\end{array}
$

\end{document}

compiles fine. But if I try square delimiters

\documentclass[11pt]{article}
\usepackage{delarray}

\begin{document}

$
\begin{array}[{cc}]
a & b\\
c & d
\end{array}
$

\end{document}

doesn't compile at all (despite the fact that this is the *same* example 
as shown at the bottom of p. 105 of Kopka & Daly - 3rd edition). To get 
square delimiters, I need to use

\documentclass[11pt]{article}
\usepackage{delarray}

\begin{document}

$
\left[
\begin{array}{cc}
a & b\\
c & d
\end{array}
\right]
$

\end{document}

OK, I suppose I can work with that (although it puzzle me why delarray 
only seems to play nice with () delimiters -- if true, pretty limited, 
no pun intended).

But, the \left \right approach doesn't seem to 'play nice' with the 
tabular environment. Ultimately, I'm trying to generate something like 
the following

\documentclass[11pt]{article}
\usepackage {delarray}
\begin{document}

\begin{tabular}{ c  @{} c  }
     &\begin{tabular}{cc} A & B \end{tabular} \\
  \begin{tabular} {c} A \\ B \end{tabular}
  &
  \begin{tabular} ({cc})
   1 & 2 \\
   3 & 4\\
   \end{tabular}
\end{tabular}

\end{document}

but with square delimiters. If I try

\documentclass[11pt]{article}
\usepackage {delarray}
\begin{document}

$
\begin{tabular}{ c  @{} c  }
     &\begin{tabular}{cc} A & B \end{tabular} \\
  \begin{tabular} {c} A \\ B \end{tabular}
  &
  \left(
  \begin{tabular} {cc}
   1 & 2 \\
   3 & 4\\
   \end{tabular}
  \right)
\end{tabular}
$

\end{document}

doesn't compile. Which means that

\documentclass[11pt]{article}
\usepackage {delarray}
\begin{document}

$
\begin{tabular}{ c  @{} c  }
     &\begin{tabular}{cc} A & B \end{tabular} \\
  \begin{tabular} {c} A \\ B \end{tabular}
  &
  \left[
  \begin{tabular} {cc}
   1 & 2 \\
   3 & 4\\
   \end{tabular}
  \right]
\end{tabular}
$

\end{document}


won't compile either.

If only blkarray weren't broken. ;-)

Suggestions/solutions?

Thanks in advance...

see 'texdoc delarray'

and you will see why [ does not work as expected, array is changed such 
that

\begin{array}[t]({c})

is supported

have you tried blkarray instead? delarray is from 1994 (apparently)

SYNTAX ? \begin{array} [ outer alignment ]
                        <delarray left> { preamble } <delarray right>

Well. So: \begin{array} [ => [{cc}] => outer alignment = {cc}
                                     => where is the preamble ????


$\begin{array} [c] [{cc}] ... \end{array}$

With tabu it's also possible to say:

$\begin{tabu} [] [{cc}] ... \end{tabu}$

then the default outer alignment is used... next release next ;-)

Regards.

In fact, braces are mandatory around the tabular/array preamble, at
least when delarray.sty is loaded. For tabu they are always mandatory.

Then I will implement the test so that
    $\begin{tabu} [{cc}]  ...
will be possible !

Thanks.

So, only () delimiters? Alas, then useless for me.

blkarray is broken, and delarray is overly limited. So, for the moment, 
there seems to be no way to take the following and put square brackets 
around the matrix. I can hear my editor now ('Gee, you could do this 
with MathType in Word in about 10 seconds...').

Free virtual beer for anyone who can figure out a solution. All I want 
is to generate something like...(where the braces are contiguous on left 
and right sides).

        A  B
     A [1  2]
     B [3  4]


\documentclass[11pt]{article}
\usepackage {delarray}
\begin{document}

$
\begin{tabular}{ c  @{} c  }
     &\begin{tabular}{cc} A & B \end{tabular} \\
  \begin{tabular} {c} A \\ B \end{tabular}
  &
  \begin{tabular} ({cc})
   1 & 2 \\
   3 & 4\\
   \end{tabular}
\end{tabular}
$

\end{document}

Why do I need one? Never needed one for any other tables I've generated. 
I digress...

So

$
\begin{array}[alignment][{cc}]
a & b\\
c & d
\end{array}
$

works. Thanks -- so apparently, alignment is needed only for non-() 
delimiters? Strange...

I do not quite see the problem

\documentclass[11pt]{article}
\usepackage{blkarray}

\begin{document}

\[
\begin{blockarray}{ccc}
  & A & B\\
  \begin{block}{c[cc]}
    A & 1 & 2 \\
    B & 3 & 4\\
  \end{block}
\end{blockarray}
\]

\end{document}

seem to give me what you asked for

The default *outer* alignment for array is centered [c]. Normal in
math mode ! The default for tabular is [c] as well while for tabu
it is [c] in math mode and [t] in text mode...

As Lars said: TeX reads:  \begin{array} [

and then while it sees "the character [" it thinks "there is an outer
alignment specification". U Understand ?

So you need to give an *explicit* *outer* alignment spec only when
you use brackets delimiters [ and ].

Now I thank you because I improved tabu in order not to get into this
problem:   TeX sees   "the character ["    and looks forward
    then it sees  "the character {" and thinks "it's not the outer
alignment but the preamble..."

As long as the outer alignment il always a single letter, the user
who writes [{c}] for a centered outer alignment is wrong...

Well that's all folks: with brackets, array and tabular require an
explicit outer alignement specification.

Best regards.

no.  the doc shows an example with \{\} delimiters, and

  \begin{array}[t][{cc}]

works for me.

if you omit the optional argument, and then try for [] delimiters, the
environment will be confused enough to imagine that you're giving it an
optional argument.  hence the structure of my example, with the optional
argument given even though not strictly (otherwise) needed.

You can use also

\begin{array}\lbrack{...}\rbrack

or any other pair of delimiters. Did you try the bmatrix
environment of amsmath?
