This is the last row you should show/print to include the whole spreadsheet. 

Different from TFlexCelImport.MaxRow , this property includes images. 

Different from MaxPrintableRow, this property includes unused but formatted rows at the bottom. 

For example, suppose that you have an spreadsheet with one cell, A1="This is a test", and an image on cell B2: 

TFlexCelImport.MaxRow is 1, as this is the last row used. 

MaxVisibleRow will be 2, as there is an image on B2, even when B2 is empty.
