A dataset can be embedded directly using the `data` property, or it can be linked to a raw file using the `path`. If the latter, optional format and parsing options can be applied to aid interpreting the file contents. resource profile: 'datatable' Signature: ```typescript export interface DataTableSchema extends ResourceSchema ``` Extends: [ResourceSchema](./schema.resourceschema.md) ## Properties | Property | Modifiers | Type | Description | | --- | --- | --- | --- | | [columns?](./schema.datatableschema.columns.md) | | number | (Optional) Number of columns in the data. | | [data?](./schema.datatableschema.data.md) | | string \| unknown\[\] | (Optional) Option to embed the data directly in the JSON descriptor.
