I need you to create a regular expression for converting the following document into a table:

```
$$TEXTLINES$$
```

The table contains the following columns:

$$COLUMNS$$

Output the regex as the following JSON:
```json
{
  "regex" : "<regular expression>",
  "NumberOfGroups": <number of groups in the expression>,
  "Group1" : "<column name>",
  ...,
  "GroupN" : "<column name>",
}
```

The regular expression should use numbered groups, starting with one, and include line start/end markers (^ and $).
