end

#cell_at_column(index) ⇒ Object

returns the cell of the current row at the given column index (starting from 0), taking into account conSpans of other cells.

returns nil if index is greater than the number of columns of this row.

  end
  nil
end

#cell_at_column!(index) ⇒ Object

returns the cell of the current row at the given column index (starting from 0), taking into account conSpans of other cells.

raises exception if the cell does not exist (that is, index is greater than the number of columns of this row).
