# Features

* Parsing table data from CSV (with simple automatic delimeter detection), SQL or Cassandra outputs
* Filtering columns based on certain criteria. Filter attempts to correctly interpret numbers (but not floating point numbers yet), instead of using only string to string comparison.

* Generate table with test data

```bash
table --generate 10 --add id=%{uuid} --add status='%{randomChoice(on,off)}' --add amount='%{random(1,10)}'
```
Produces:

```
╭──────────────────────────────────────┬────────┬────────╮
│ id │ status │ amount │

* Generate insert statements with test data

```bash
table --print 'INSERT INTO orders (id, amound, status) VALUES (\'%{uuid()}\', %{random(1, 1000)}, \'%{randomChoice(ok,pending,failed)}\');' --generate 3
```

Outputs:

```
INSERT INTO orders (id, amound, status) VALUES ('BCDABED0-A4EB-4C90-9423-4AA0269A39D7', 266, 'pending');
INSERT INTO orders (id, amound, status) VALUES ('64FC986A-93A1-4579-B7F5-896CD7757AE8', 462, 'failed');
INSERT INTO orders (id, amound, status) VALUES ('74CB99C8-D23F-4081-901B-8634187E4269', 529, 'ok');
```
