Steps to Reproduce

1. load the attached file as a byte array
or run keikai.test/io.keikai.model.ImporterTest.columnArrayOrder()

Current Result

Caused by: java.lang.IllegalStateException: Can't setup an overlapped column array 3,3 overlppaed io.keikai.model.impl.ColumnArrayImpl@676cac62[0-3]
at io.keikai.model.impl.SheetImpl.setupColumnArray(SheetImpl.java:288)
at io.keikai.importer.XlsxImporter.importColumn(XlsxImporter.java:1637)
at io.keikai.importer.XlsxImporter.imports(XlsxImporter.java:292)

Expected Result

no error

Debug Information

1. zss 3.9.6 doesn't have this bug
2. zss set column array from low column number e.g. 1, 2,3...
But keikai set column array from high number e.g. 4-16383, 3-3
This causes unexpected overlapping.
3. It's better to comment about this column array set up order.
