Table.Unpivot
Table.Unpivot(table as table, pivotColumns as list, attributeColumn as text, valueColumn as text) as table
Kääntää taulukon sarakejoukon määrite–arvo-pareiksi yhdistettynä kunkin rivin muiden arvojen kanssa.
Ota sarakkeet "a", "b" ja "c" taulukossa ({[ key = "x", a = 1, b = null, c = 3 ], [ key = "y", a = 2, b = 4, c = null ]})
ja poista niiden pivotointi, jotta niistä tulee määrite–arvo-pareja.
käyttö
Table.Unpivot(
Table.FromRecords({
[key = "x", a = 1, b = null, c = 3],
[key = "y", a = 2, b = 4, c = null]
}),
{"a", "b", "c"},
"attribute",
"value"
)
Output
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]
})
