# Manual table

The Manual Table Editor lets you paste or type values directly into the plugin when you’re working with compact datasets. It keeps a 100 × 50 grid in sync with the chart preview.

### When to use it

* You have fewer than \~100 rows and want to tweak numbers on the fly.
* You’re exploring scenarios without access to the original spreadsheet.
* You need to adjust imported data after the fact without switching sources.

### Key UI areas

1. **Header row** — first row contains column names. The first column is treated as categories; subsequent columns become series.
2. **Grid body** — double-click to edit a cell, press `Enter` or `Tab` to move around quickly.

### Workflow

1. Select **Table → Manual** from the Data tab.
2. Paste data from your spreadsheet (cmd/ctrl + V) or type values manually.
3. Optionally rename the first row to control legend labels.

### Troubleshooting

| Problem                       | What to check                                                                  |
| ----------------------------- | ------------------------------------------------------------------------------ |
| Numbers disappear after paste | Ensure the source uses plain text or numbers; merged cells can break the grid. |
| Chart skips some rows         | Verify the first column has values—empty labels are excluded.                  |
| Performance slows down        | Reduce rows/columns or switch to CSV/Google Sheets for larger datasets.        |
