For a multi-page table, insert continuation indicators on each page.

Sometimes a file can contain multiple long tables, each spanning over =>2 pages.
These tables may have identical structure. A typical example is a User's Manual
of an application, which has identically structured tables that explain
different menus.

When the reader sees pages after pages of identically strutured tables, it is
very difficult for him to distinguish between these tables. So there must be a
provision to indicate when one table ends and when another begins.

Secondly, the caption of a multi-page table appears only once; not on each page.
So if the user sees a middle piece of the table, he can't tell which table it
is. He has to scroll down till the end of the table (or scroll up till the top)
to check the caption. Ideally, he should be able to glance at the top/bottom of
the current page and tell which table this is.

For better readability, the following should be provided:
1. Wherever the table breaks over a page-break, Writer should automatically
insert a right-aligned "To be continued on next page..." sentence. (Provide a
default sentence, but also let the author edit the sentence.)

2. Writer should automatically repeat the table's caption on each page.
(Typically, this would include the table number and a title).

3. On the next page, where the table continues, Writer should insert a
left-aligned "(...Continued from the previous page)" sentence to indicate that
this part of the table is in continuation. (Provide a default sentence, but also
let the author edit the sentence.)

Note that the author cannot insert these sentences manually, because the
location of the table-break point keeps shifting as the file is edited.
