Dev fix: Volumne visiblity with scrolling enabled would misalign columns

- When creating the new visiblity methods, I forgot to have the table do
  a scroll draw to have the columns align correctly for the header and
  body. This commit fixes that.

- Also update the column visiblity example to use jQuery events rather
  than DOM0 events.
