Initializes a new instance of CellRange.
CellRange = function(
firstRow,
lastRow,
firstColumn,
lastColumn
)
firstRow
Zero-based index of the first row in the cell range.
lastRow
Zero-based index of the last row in the cell range.
firstColumn
Zero-based index of the first column in the cell range.
lastColumn
Zero-based index of the last column in the cell range.
The CellRange constructor initializes a new CellRange object with the specified boundaries. The boundaries define a rectangle of cells in a spreadsheet, starting from the firstRow and firstColumn to the lastRow and lastColumn .
This constructor does not perform any operations on the cells within the range itself. It merely defines the range, which can then be used in conjunction with spreadsheet manipulation methods.
