An exception could not be caught when calling XLWorksheet::range on the empty sheet.

An exception could not be caught when calling XLWorksheet::range on the empty sheet. The cause of the problem lies in the noexcept specifier of the function XLCellReference XLWorksheet::lastCell() const noexcept, which prevents exception propagation.

XLCellReference XLWorksheet::lastCell() const noexcept { return { rowCount(), columnCount() }; }

XLCellReference::XLCellReference(uint32_t row, uint16_t column)
{
if (!addressIsValid(row, column)) throw XLCellAddressError("Cell reference is invalid");
setRowAndColumn(row, column);
}

confirmed, thank you for the bug report! I'll work on this

out of interest: would you think it's better to auto-return a range that contains only the cell A1, or throw an exception that can be caught?
I am inclined to return a default-constructed range (contains only A1) if XLWorksheet::rows() == 0

Please have a look at development-aral branch: 592eed2 - this prevents XLSheet::lastCell from throwing an exception for rowCount or columnCount == 0
