Specificera den absoluta positionen för pivotposten

Contents
[ ]

Följande provkod skapar en pivottabell och sedan specificerar den pivotpostens positioner i samma föräldernod. Du kan ladda ner käll-Excel- och utdata-Excel-filer för din referens. Om du öppnar utdata-Excel-filen kommer du att se att pivotposten “4H12” är på 0: e position i förälder “K11” och “DIF400” är på 3: e position. På samma sätt är CA32 på position 1 och AAA3 är på position 2.
