Table.Pivot

Roteert aan de hand van kolommen die paren kenmerk-waarde vertegenwoordigen, de gegevens in de kenmerkkolom naar een kolomkop.

Syntax​

Table.Pivot(
    table as table,
    pivotValues as list,
    attributeColumn as text,
    valueColumn as text,
    optional aggregationFunction as function
) as table

Remarks​

Roteert aan de hand van kolommen die paren kenmerk-waarde vertegenwoordigen, de gegevens in de kenmerkkolom naar een kolomkop.

Examples​

Example #1​

De waarden "a", "b" en "c" in de kenmerkkolom van de tabel <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> nemen en die draaien in hun eigen kolom.

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​

De waarden "a", "b" en "c" in de kenmerkkolom van de tabel <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> nemen en die draaien in hun eigen kolom. Bij het kenmerk "c" voor sleutel "x" horen meerdere waarden, dus gebruik de functie List.Max om het conflict op te lossen.

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]
})
