public final class Offset extends java.lang.Object implements Function
OFFSET returns an area reference that is a specified number of rows and columns from a reference cell or area.
Syntax:
OFFSET(reference, rows, cols, height, width)
reference is the base reference.
rows is the number of rows up or down from the base reference.
cols is the number of columns left or right from the base reference.
height (default same height as base reference) is the row count for the returned area reference.
width (default same width as base reference) is the column count for the returned area reference.

Function
(在接口函数中求值)
args
- the evaluated function arguments. Empty values are represented with
BlankEval
or
MissingArgEval
, never
null
.
(args - 评估的函数参数。空值用 BlankEval 或 MissingArgEval 表示,绝不为 null。)
srcCellRow
- row index of the cell containing the formula under evaluation
(srcCellRow - 包含计算公式的单元格的行索引)
srcCellCol
- column index of the cell containing the formula under evaluation
(srcCellCol - 包含正在评估的公式的单元格的列索引)
ErrorEval
, never
null
.
Note - Excel uses the error code
#NUM! instead of IEEE
NaN, so when numeric functions evaluate to
Double.NaN
be sure to translate the result to
ErrorEval.NUM_ERROR
.
(评估结果,可能是 ErrorEval,绝不为空。注意 - Excel 使用错误代码 #NUM!而不是 IEEE NaN,因此当数值函数计算为 Double.NaN 时,请务必将结果转换为 ErrorEval.NUM_ERROR。)
