# Handling merged cells

Using the following payload you can add data to all cells, including the merged cells. 

1. Select the shape by `name` you want to modify. See [here](/knowledge-base/finding-shape-names.md) to find shape names.
2. Each list in \`data\_cells\` denotes a row in your table. 
3. Each row list must have the same number of list objects. Data from the last merged cell will be rendered to the merged cell in your table shape.

{% hint style="info" %}
Limitation - currently, if your table shape has a merged cell, your payload must have the same number of data points otherwise it will fail. This will be improved very soon. 
{% endhint %}
