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