Problem Description:

When using API to get the row index of a named range of cells, it returns a wrong row value.

for example a named range has 6 cells and its first row is at row 12, so namedRange.getRow() should return 11 but it returns 0.

java.lang.AssertionError: 
Expected: <11>
     but: was <0>
	at org.hamcrest.MatcherAssert.assertThat(MatcherAssert.java:20)
	at org.junit.Assert.assertThat(Assert.java:865)

Reproducing Steps:

1. run test case
run automatic test case CellDataTest.testNamedRange() of the project zss.test of zkspreadsheet

2. use attached file.
use API to get row like Ranges.range(sheet, "TestRange1").getRow()
