ConTeXt mkiv: Footnote inside tabulation

Question

I need to include a \footnote inside a tabulation environment. I adapted the example from ConTeXt wiki, but at compiling the content between \starttabulatehead and \stoptabulatehead doesn't show up and the content appears aligned to the left:

\starttext
\placetable[here]{Tabla.}
{\startlocalfootnotes\placelegend
{\starttabulatehead
\NC A \NC B \SR
\stoptabulatehead}
{\starttabulate[|l|l|]
\NC C\footnote{Nota al pie.} \NC D \NR
\stoptabulate}
{\placelocalfootnotes}
\stoplocalfootnotes}
\stoptext

Am I missing something here? Thanks!

The following should do what you want:

\starttext

\startplacetable [title=Tabla]
  \startlocalfootnotes

    \starttabulatehead
      \NC A \NC B \SR
    \stoptabulatehead

    \starttabulate[|l|l|]
      \NC C \footnote{Nota al pie.} \NC D \NR
    \stoptabulate

    \placelocalfootnotes
  \stoplocalfootnotes
\stopplacetable

\stoptext

To prevent the table from floating add the location=here option. If you want the table to be centred use \midaligned:

\startplacetable [title=Tabla, location=here]
  \startlocalfootnotes

    \starttabulatehead
      \NC A \NC B \SR
    \stoptabulatehead

    \midaligned{\vbox{%
      \starttabulate[|l|l|]
        \NC C \footnote{Nota al pie.} \NC D \NR
      \stoptabulate}}

    \midaligned{\placelocalfootnotes}
  \stoplocalfootnotes
\stopplacetable

Edit:

As Aditya mentioned in the comment, a better solution than the \midaligned is to use the new legend mechanism. Here an example:

\startplacetable [title=Tabla]
  \startlocalfootnotes

    \starttabulatehead
      \NC A \NC B \SR
    \stoptabulatehead

    \startplacelegend [location=top] %% default is bottom
      \startcontent
        \vbox\bgroup
          \starttabulate[|l|l|]
            \NC C \footnote{Nota al pie.} \NC D \NR
          \stoptabulate
        \egroup
      \stopcontent
      \startcaption
        \placelocalfootnotes
      \stopcaption
    \stopplacelegend

  \stoplocalfootnotes
\stopplacetable
