/*
* The implementation of tables differs greatly between version 3.0
* (in riched20.dll) and version 4.1 (in msftedit.dll) of richedit controls.
* Currently Wine is not distinguishing between version 3.0 and version 4.1,
* so v4.1 is assumed unless v1.0 is being emulated (i.e. riched32.dll is used).
* If this lack of distinction causes a bug in a Windows application, then Wine
* will need to start making this distinction.
*
* Richedit version 1.0 - 3.0:
* Tables are implemented in these versions using tabs at the end of cells,
* and tab stops to position the cells. The paragraph format flag PFE_TABLE
* will indicate that the paragraph is a table row. Note that in this
* implementation there is one paragraph per table row.
*
* Richedit version 4.1:
* Tables are implemented such that cells can contain multiple paragraphs,
* each with its own paragraph format, and cells may even contain tables
* nested within the cell.
*
* There is also a paragraph at the start of each table row that contains
* the rows paragraph format (e.g. to change the row alignment to row), and a
* paragraph at the end of the table row with the PFE_TABLEROWDELIMITER flag
* set. The paragraphs at the start and end of the table row should always be
* empty, but should have a length of 2.
*
* Wine implements this using display items (ME_DisplayItem) with a type of
* diCell. These cell display items store the cell properties, and are
* inserted into the editors linked list before each cell, and at the end of
* the last cell. The cell display item for a cell comes before the paragraphs
* for the cell, but the last cell display item refers to no cell, so it is
* just a delimiter.
