# Tables and charts

> Edit structured data, table formatting, and chart presentation.

Use table editing for structured comparisons and values that need row-and-column alignment.

## Prepare structured data

Before editing a table or chart, confirm:

* Descriptive category and series names.
* Units such as currency, percentages, counts, durations, or rates.
* Exact reporting periods and frequencies.
* The meaning of zero, unavailable, and not applicable values.
* Which file, sheet, or export is the source of truth.

## Edit a table

  <Step title="Select the table">

  <Step title="Update content">
    Edit cell text and values. Add or remove rows and columns when the available controls support the change.
  </Step>

  <Step title="Apply formatting">
    Update the header, cells, borders, fills, typography, alignment, and spacing with the table controls.
  </Step>

  <Step title="Verify the data">

  </Step>
</Steps>

## Choose the right chart

| Goal                         | Suitable chart             |
| ---------------------------- | -------------------------- |
| Compare categories           | Bar or horizontal bar      |
| Show change over time        | Line or area               |
| Show contribution to a whole | Stacked bar, pie, or donut |
| Show relationships           | Scatter or bubble          |
| Compare several measures     | Radar                      |

Use a table when exact values matter more than the overall pattern.

<Warning>
  Visual editing does not verify table data. Confirm every important value after making structural or AI-assisted changes.
