Examples

Take the values "a", "b", and "c" in the attribute column of table ({ [ key = "x", attribute = "a", value = 1 ], [ key = "x", attribute = "c", value = 3 ], [ key = "y", attribute = "a", value = 2 ], [ key = "y", attribute = "b", value = 4 ] }) and pivot them into their own column.

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")

Table.FromRecords({[ key = "x", a = 1, b = null, c = 3 ], [ key = "y", a = 2, b = 4, c = null ]})

Take the values "a", "b", and "c" in the attribute column of table ({ [ 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 ] }) and pivot them into their own column. The attribute "c" for key "x" has multiple values associated with it, so use the function List.Max to resolve the conflict.

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)

Table.FromRecords({[ key = "x", a = 1, b = null, c = 5 ], [ key = "y", a = 2, b = 4, c = null ]})
