2、数组排序函数
VBA没有为我们提供数组排序功能,这是一个缺憾。实际开发中,人们或者书写冗长的排序语句,或者干脆用单元格排序语句来变通代替,也可勉强解决问题,二者的弊端显而易见。此函数可实现最多三个关键字的排序,基本满足实战需要。如有更多关键字排序需求的,可根据此代码思路,进一步深化函数的功能。
Public Function sortarr(arr, key1, order1, Optional key2 = 0, Optional order2 = 1, Optional key3 = 0, Optional order3 = 1)
Rem 数组排序函数
Rem arr为被排序数组,含key参数为排序字段,含order参数为排序次序,key和order两两一组,最多三组,最多可对三个字段排序,后两组排序参数可省略
Dim i, ii, c, code, tmp, code1, code2, tmparr(), v1, v2, v3, v4, v5, v6, tmp0, tmp1, tmp2, tmp3, tmp4
If LBound(arr) = 0 Then
Rem 一维数组排序
If order1 = 1 Then code = "<" Else code = ">"
For i = 0 To UBound(arr) - 1
For ii = i + 1 To UBound(arr)
tmp = Evaluate(arr(ii) & code & arr(i))
If tmp = True Then tmp1 = arr(i): arr(i) = arr(ii): arr(ii) = tmp1
Next
Next
Else
Rem 二维数组排序
ReDim tmparr(1 To UBound(arr, 2))
If key2 = 0 And key3 = 0 Then
Rem 一个关键字排序
If order1 = 1 Then code1 = "<" Else code1 = ">"
For i = 1 To UBound(arr) - 1
For ii = i + 1 To UBound(arr)
v1 = arr(ii, key1): v2 = arr(i, key1)
'evaluate括号中的字符串两面要加引号
