I need a table that has local notes, but have not been able to get them into the proper position (at the left margin of the table) or  the the proper length ( extending full length of table if needed). What am I missing in the following reduced example?

\starttext

\startlocalfootnotes[conversion=character]
\placetable[][]
{}
\placelegend
{\starttables[|p|p|p|p|p|p|]
\NC numbers
\NC (*) \footnote{This is the first footnote.}
\NC stuff \footnote{This is the second footnote.}
\NC stuff\footnote{This is the third footnote.}
\NC more stuff\footnote{This is the fourth footnote}
\NC and yet more \NC\SR
 \HL
\stoptables}
{\placelocalfootnotes}
\stoplocalfootnotes

\stoptext
