Table.ExpandTableColumn
Table.ExpandTableColumn(table as table, column as text, columnNames as list, optional newColumnNames as nullable list) as table
Expands tables in table
[column
] into multiple rows and columns. columnNames
is used to select the columns to expand from the inner table. Specify newColumnNames
to avoid conflicts between existing columns and new columns.
Expand table columns in [a]
in the table ({[t = {[a=1, b=2, c=3], [a=2,b=4,c=6]}, b = 2]})
into 3 columns [t.a]
, [t.b]
and [t.c]
.
Usage
Table.ExpandTableColumn(
Table.FromRecords({
[
t = Table.FromRecords({
[a = 1, b = 2, c = 3],
[a = 2, b = 4, c = 6]
}),
b = 2
]
}),
"t",
{"a", "b", "c"},
{"t.a", "t.b", "t.c"}
)
Output
Table.FromRecords({
[t.a = 1, t.b = 2, t.c = 3, b = 2],
[t.a = 2, t.b = 4, t.c = 6, b = 2]
})
