`array.from()` constructs a table from an array of records.

Each record in the array is converted into an output row or record. All records must have the same keys and data types.

##### Function type signature

```js
(<-rows: [A]) => stream[A] where A: Record
```

For more information, see [Function type signatures](/flux/v0/function-type-signatures/).

## Parameters

### rows

Array of records to construct a table with. Default is the piped-forward array (`<-`).

## Examples

-   [Build an arbitrary table](#build-an-arbitrary-table)
-   [Union custom rows with query results](#union-custom-rows-with-query-results)

### Build an arbitrary table

```js
import "array"

rows = [{foo: "bar", baz: 21.2}, {foo: "bar", baz: 23.8}]

array.from(rows: rows)
```

[](#view-example-output)

#### Output data

| foo | baz |
| --- | --- |
| bar | 21.2 |
| bar | 23.8 |

### Union custom rows with query results

```js
import "influxdata/influxdb/v1"
import "array"

tags = v1.tagValues(bucket: "example-bucket", tag: "host")

wildcard_tag = array.from(rows: [{_value: "*"}])

union(tables: [tags, wildcard_tag])
```
