Transposes the table contents so rows become columns and columns become rows.

Signature

Parameters

• ...rest: the names to give columns once transposed
• --header-row (-r): treat the first row as column names
• --ignore-titles (-i): don't transpose the column names into values
• --as-record (-d): transfer to record if the result is a table and contains only one row
• --keep-last (-l): on repetition of record fields due to header-row, keep the last value obtained
• --keep-all (-a): on repetition of record fields due to header-row, keep all the values obtained

Input/output types:

input	output
record	table
table	any

Examples

Transposes the table contents with default column names

> [[c1 c2]; [1 2]] | transpose
╭───┬─────────┬─────────╮
│ # │ column0 │ column1 │
├───┼─────────┼─────────┤
│ 0 │ c1      │       1 │
│ 1 │ c2      │       2 │
╰───┴─────────┴─────────╯

Transposes the table contents with specified column names

> [[c1 c2]; [1 2]] | transpose key val
╭───┬─────┬─────╮
│ # │ key │ val │

│ 0 │ c1  │   1 │
│ 1 │ c2  │   2 │
╰───┴─────┴─────╯

Transposes the table without column names and specify a new column name

> [[c1 c2]; [1 2]] | transpose -i val
╭───┬─────╮
│ # │ val │
├───┼─────┤
│ 0 │   1 │
│ 1 │   2 │

Transfer back to record with -d flag

> {c1: 1, c2: 2} | transpose | transpose -i -r -d
