Table.Pivot
Wandelt bei Angabe eines Spaltenpaars, das Attribut-Wert-Paare darstellt, die Daten in der Attributspalte in Spaltenüberschriften um.
Syntax
Table.Pivot(
table as table,
pivotValues as list,
attributeColumn as text,
valueColumn as text,
optional aggregationFunction as function
) as table
Remarks
Wandelt bei Angabe eines Spaltenpaars, das Attribut-Wert-Paare darstellt, die Daten in der Attributspalte in Spaltenüberschriften um.
Examples
Example #1
Pivotiert die Werte "a", "b" und "c" aus der Attributspalte der Tabelle <code>({ [ key = "x", attribute = "a", value = 1 ], [ key = "x", attribute = "c", value = 3 ], [ key = "y", attribute = "a", value = 2 ], [ key = "y", attribute = "b", value = 4 ] })</code> jeweils in eine eigene Spalte.
Table.Pivot(
Table.FromRecords({
[key = "x", attribute = "a", value = 1],
[key = "x", attribute = "c", value = 3],
[key = "y", attribute = "a", value = 2],
[key = "y", attribute = "b", value = 4]
}),
{"a", "b", "c"},
"attribute",
"value"
)
Result:
Table.FromRecords({
[key = "x", a = 1, b = null, c = 3],
[key = "y", a = 2, b = 4, c = null]
})
Example #2
Pivotiert die Werte "a", "b" und "c" aus der Attributspalte der Tabelle <code>({ [ key = "x", attribute = "a", value = 1 ], [ key = "x", attribute = "c", value = 3 ], [ key = "x", attribute = "c", value = 5 ], [ key = "y", attribute = "a", value = 2 ], [ key = "y", attribute = "b", value = 4 ] })</code> jeweils in eine eigene Spalte. Da dem Attribut "c" für den Schlüssel "x" mehrere Werte zugeordnet sind, muss die Funktion "List.Max" verwendet werden, um den Konflikt zu lösen.
Table.Pivot(
Table.FromRecords({
[key = "x", attribute = "a", value = 1],
[key = "x", attribute = "c", value = 3],
[key = "x", attribute = "c", value = 5],
[key = "y", attribute = "a", value = 2],
[key = "y", attribute = "b", value = 4]
}),
{"a", "b", "c"},
"attribute",
"value",
List.Max
)
Result:
Table.FromRecords({
[key = "x", a = 1, b = null, c = 5],
[key = "y", a = 2, b = 4, c = null]
})
