CATable::Subscript

ADE User Guide > ADE Server Class Reference > CATable

Subscript(indexObj, label)

Returns a slice of a table for which index «indexObj» is equal to «label». It returns a new CATable object with one fewer dimension than the original table. When used on a DefTable, the sliced DefTable acts as a SubTable, changing elements in the slice of the original table.

参 数

indexObj

CAObject

label

variant – the label in the index

返回值

CATable

示例用法

CATable tab = obj. ResultTable;
CAIndex in1 = tab. GetIndexObject("In1");
CATable subTab = obj.Slice(in1,1)

说明

DefTable（确定性表）上 CATable::Subscript(..) 的使用在4.2.3中介绍，充当一个 子表。

当应用于一个1维表格、结果为0维表格结果（只包含一个 基元值的非数组）时。此时， CATable::AtomicValue方法用来访问该值。
