Displaying nested arrays?

[gamov]

I have this:

tp [[1,2,3],[44,55,66]], :second, :last, object_class: lambda{|ary| ary.first}

which I expect something like:

SECOND	LAST	OBJECT_CLASS
2	3	1
55	66	44

but I get a:

NoMethodError: undefined method `first' for 1:Fixnum
    from (irb):181:in `block in irb_binding'
    from /Users/gamov/.rvm/gems/ruby-1.9.3-p545@ector/gems/table_print-1.5.1/lib/table_print/fingerprinter.rb:38:in `call'

If you try without the lambda, you get the improbable following:

>> tp [[1,2,3],[44,55,66]], :first, :second
FIRST          | SECOND
---------------|-------
Method Missing | 1     
Method Missing | 2     
Method Missing | 3     
Method Missing | 44    
Method Missing | 55    
Method Missing | 66  

It would be very handy to be able to display arrays of arrays with table_print. Unfortunately, currently, it seems that tp flatten them before displaying the table.

or am I doing something wrong?

That's a bug. There's a place where I wrap the dataset with Array() that's messing it up. Unfortunately the fix is non-trivial.

Just came across this. Could you point out where this bug is?
