Table::Table Properties::Text Flow has the option to "Allow row to break across
pages and columns".

Help states: "Allows a page break or column break inside a row of the table.
This option is not applied to the first row in a table if the Repeat Heading
option is selected."

However, even without Repeat Heading selected, there appears to be no way to
implement a page break in a table cell (such that the next line in that cell
starts at the top of the next page). Currently the only workaround is to insert
Returns until the cell contents flow onto the next page, which is no good if
further content is added above at a later stage.

I'm posting this as a defect rather than an enhancement, as the Help implies
that this functionality should already be present. However, it may be a defect
in the Help instead, if what's really meant is just that the cell CAN break
across pages/columns, rather than that the user CAN implement that break - I am
not the only user to read it and assume that the user can therefore insert a
page/column break there.

(Note that this functionality is also a requirement for the standard EU Europass
CV layout.)
