Table CSV and PDF export
Built-in CSV download
Table widgets can expose a download control that exports the current table data as CSV. Enable the download option in the table's property pane where available.
PDF via JS
For PDF export, apps can use a JS Object with a PDF library (for example jsPDF) to render table rows. See the engineering note in the repository (project-docs/development/table-export-pdf.md) for a sample pattern, then adapt it to your table's columns.
