CATable::GetDataByElements(indexPositions)

根据«indexPositions»检索输入表格单元的值，«indexPositions»沿表格中索顺序指明位置（从1开始）。

此参数通过使用索引方向上的位置说明表格单元的坐标，position 1为第一个元素位置（CATable::GetDataByLabels通过使用索引标签来实现）。当表格位1维时，«indexPositions»必须是一个整数值。否则，«indexPositions»必须是一个包含N个数的数组（表格维度为N）。

维度的顺序，同它们在«indexPositions»中所列出一样，由前面调用CATable::SetIndexOrder决定。

返回值是表格单元的值。该值返回的方式由CATable::RenderingStyle决定。

当结果表是零维度时（也就是说，一个基元值，非数组），你必须使用CATable::AtomicValue来访问并获取该值。

示例

在VB中

dim editTab as CATable = var2d.DefTable

dim coord(1)   ' Contains two elements, (0) and (1)
coord(0) = 3
coord(1) = 2
editTab.SetIndexOrder( Split("I,J",",") )

ET = editTab.GetDataByElements(coord)

dim resTab as CATable = var2d.ResultTable
resTab.SetIndexOrder( Split("I,J",","))
RT = resultTab.GetDataByElements(coord)

RT1 = var1d.ResultTable.GetDataByElements(4)

错误代码

24 – “下标必须是一个变体数组”
25 – “下标无法访问”
26 – “数组下界无法访问”
27 – “数组上界无法访问”
28 – “必须最少指定表格中的一个元素”
30 – “位置不存在”
