Abcd describes our Excel to use this way, which of which of which SHEET is, which is output.
It has established data to export to Excel correspondence.
CSSClass is description style class
DBTOEXCELRELATION is a description of the total data correspondence class (it may contain multiple Sheet correspondence)
FixEdItem is a fixed grid
RelationItem is the data area corresponding class (it is a recursable class)
SheetMapRelation This is an Excelsheet class (which contains FixedItem, RELATIONITEM, CSSCLASS)
As shown below:
