4 Worksheet/Workbook Stream
4.7 Cell Table and Row Blocks
4.7.1 Cell Table
Definition: Cell Table
The Cell Table describes all cells in a sheet, together with all row and column settings for that sheet.
Structure of the Cell Table in the Worksheet Stream (BIFF2):
○ DEFAULTROWHEIGHT ➜5.31
○ DEFCOLWIDTH ➜5.32
○○ COLWIDTH ➜5.20
● DIMENSION ➜5.35
○○ COLUMNDEFAULT ➜5.19
○○ Row Block(s) Groups of rows with cells (➜4.7.2)
Structure of the Cell Table in the Worksheet Stream (BIFF3-BIFF4), and Sheet Substream (BIFF5-BIFF8):
○ DEFAULTROWHEIGHT ➜5.31
○ DEFCOLWIDTH ➜5.32
○○ COLINFO ➜5.18
● DIMENSION ➜5.35
○○ Row Block(s) Groups of rows with cells (➜4.7.2)
○ STANDARDWIDTH ➜5.101 (BIFF4-BIFF8 only)
4.7.2 Row Block
Definition: Row Block
All cells in the Cell Table are divided into blocks of 32 consecutive rows, called Row Blocks. The first Row
Block starts with the first used row in that sheet. Inside each Row Block there will occur ROW records describing
the properties of the rows, and cell records with all the cell contents in this Row Block.
Example: The first used cell in the sheet is located in row 10, or row 10 is the first formatted row. The first Row
Block will contain the rows 10…41, the second Row Block will contain the rows 42…73, and so on.
Each Row Block contains ROW records describing the row properties (in ascending order), followed by all cell records
in this block. The cell records are stored row by row (ascending), and in each row from left to right. A used row either
contains any (filled or formatted) cells or is changed in another way (for instance height or default formatting). If a row
is not used, there will not occur a ROW record in the Row Block.
Structure of a Row Block in the Worksheet Stream (BIFF2-BIFF4) or in the Sheet Substream (BIFF5-BIFF8):
●● ROW Properties of the used rows (➜5.88)
○○ Cell Block(s) Cell records for all used cells (➜4.7.3)
