TExcelFile.DefaultRowHidden Property
When this property is true, rows with no data are hidden by default. Note that this property only affects the visibility of empty rows. If for example row 6 is empty and you have this property true, then row 6 will be hidden. But if you write any value in a cell in row 6, then the row won't be empty anymore, and it won't be hidden anymore either.
