Method Detail

addCell

public void addCell(WritableCell cell)
             throws WriteException,
                    RowsExceededException
Adds a cell to this sheet The RowsExceededException may be caught if client code wishes to explicitly trap the case where too many rows have been written to the current sheet. If this behaviour is not desired, it is sufficient simply to handle the WriteException, since this is a base class of RowsExceededException
Parameters:
cell -  
Throws:
jxl.write..WriteException -  
RowsExceededException -  

setName

public void setName(java.lang.String name)
Sets the name of this sheet
Parameters:
name -  

setHidden

public void setHidden(boolean hidden)
Deprecated. use the SheetSettings bean instead

Indicates whether or not this sheet is hidden
Parameters:
hidden - hidden flag

setProtected

public void setProtected(boolean prot)
Deprecated. use the SheetSettings bean instead

Indicates whether or not this sheet is protected
Parameters:
prot - Protected flag
