delete issue in spreadsheetgear

There is an apparent issue.

When we delete a row from a range (e.g. someRange["1:1"].Delete()) this does not make the range 1 row smaller but keeps an empty row at the end of the range

e.g.  when we save the range this is what we get:

-13,     test-13   ,-13,  test-13    ," ""  -13   ""","  gdfgdf  test-13-t,rim   ",2001-12-29,1.7

,,,,,,,   -- new row

This is not Microsoft excel behavior – excel makes the range smaller.
