All paragraphs in tables:
|
|
|
|
sprms:
|
|
0x2416 (sprmPFInTable) indicates a paragraph is in a table
|
|
0x6649 (sprmPTableDepth) demarks the nesting depth of the paragraph
|
|
|
|
paragraph at nesting depth 1:
|
|
|
|
end of cell: 0x7
|
|
end of row: 0x7 + sprm 0x2417(sprmFTtp)
|
|
|
|
the end of a row has its own 0x7
|
|
|
|
paragraphs at nesting depth > 1;
|
|
|
|
end of cell: 0xd + sprm 0x244b(sprmPCell)
|
|
end of row 0xd + sprm 0x244b(sprmPCell) + sprm 0x244c(sprmPRow)
|
|

the end of a row has its own 0xd

// get handle for start of cell i

// return properties of row

|
|

// insert cell starting at start and ending at end into the

|
// end current row and save properties for that row, begin new row

// return number of rows in table
