— 007D H 007D H 007D H 007D H
This record specifies the width and default cell formatting for a given range of columns.
In BIFF3, if a COLINFO record is missing for a column, the width specified in the record DEFCOLWIDTH (➜5.32) is
used instead.
In BIFF4-BIFF5, the width set in this record is only used, if the corresponding bit for this column is cleared in the GCW
record (➜5.51), otherwise the column width set in the DEFCOLWIDTH record (➜5.32) is used (the STANDARD-
WIDTH record (➜5.101) is always ignored in this case).
In BIFF8, if a COLINFO record is missing for a column, the width specified in the record STANDARDWIDTH
(➜5.101) is used. If this record is also missing, the column width of the record DEFCOLWIDTH (➜5.32) is used
instead.
This record also specifies a default XF record (➜5.115) to use for cells in the columns that are not described by any cell
record (which contain the XF index for that cell). Additionally, the option flags field contains hidden, outline, and
collapsed options applied at the columns.
In BIFF2, the column width is stored in the record COLWIDTH (➜5.20) and default column formatting in the record
COLUMNDEFAULT (➜5.19).
