# Table Data Input Field
A Table field lets you add CSV-based tables to documents:
* Import a CSV file
* Edit or fill it by manually
* Use table data in calculations with other fields
* View and download results in both Guardian and Indexer.
## 1. Add this field to a policy schema
Add a Table-type field to a schema so users can work with it in forms.
Setup:
* Choose Field type: Table.
* Multiple table fields can be added in one document.
* All table fields can participate in calculations (cross-table formulas, sums, links with other fields, etc.).
## 2. Use the field while filling the form
When added to a schema, the table is shown to a user during data entry.
Available options:
* Import CSV: load a file and preview the first rows/columns.
* Export/Download CSV: download the current state of the table.
* Edit: open the table in a dialog and update cells.
* Create manually: start with an empty table and fill it by hand.
## 3. Run calculations (inside a table and with other fields)
Use table data in document formulas and logic.
Options:
* Inside a table – row/column calculations (e.g., sums, averages, etc.).
* With other form fields – via:
* AutoCalculate field (automatic calculation)
* Custom Logic Block (custom rules/logic)
## 4. Save a prefilled table as a Draft
Save an unfinished form with imported/entered table data and return to it later.
## 5. View and download results in document view
What it does:
* In Guardian, VC document view shows tables and calculated values.
* In Indexer, the same table is available for viewing and downloading.
## 6. Limits and performance
* If the table size exceeds 10 MB, manual editing in the UI is not available.
* To edit:, download the CSV, update it externally,then re-import.
* Calculations still work above 10 MB, but:
* Performance may be slower
* Preview is limited to the first rows/columns
