## Row-Wise Constructor for 'data.table'

### Description

Similar to the tibble function `tribble()`, this function allows to construct tabular data in a row-wise fashion.

The first arguments passed as formula will be interpreted as column names. The remaining arguments will be put into the resulting table.

### Usage

    rowwise_table(..., .key = NULL)

### Arguments

`...` | (`any`) Arguments: Column names in first rows as formulas (with empty left hand side), then the tabular data in the following rows.
`.key` | (`character(1)`) If not `NULL`, set the key via `data.table::setkeyv()` after constructing the table.

### Value

`data.table::data.table()`.

### Examples

    rowwise_table(
      ~a, ~b,
      1, "a",
      2, "b"
    )
