add vertical alignment for cells in Plotly Table (plotly.graph_objects.Table)

Hi,

I am working on a table with custom styling, and it seems that vertical alignment of cells is not possible using the plotly.graph_objects.Table, only horizontal alignment.

I posted a question on the Plotly Community site to see if anyone knew of a way to do vertical alignment, but they confirmed it isn't possible with the code as is (link to post).

Any thoughts about how to update the current code to enable vertical alignment? I am not too familiar with the Plotly code base and plan on cloning a copy to experiment with adding this feature.

It seems like at least a few others have wanted this feature as well:

• https://stackoverflow.com/questions/67037418/plotly-table-vertical-align-text-in-cells
• https://stackoverflow.com/questions/66698852/plotly-table-how-to-align-header-vertical-and-horizontal

Documentation references:

• https://plotly.com/python/table/
• https://plotly.github.io/plotly.py-docs/generated/plotly.graph_objects.Table.html

Thank you,
Chad

Start with plotly.graph_objects.Table and the linked Plotly table documentation to understand the existing horizontal-alignment behavior and the requested vertical-alignment option. The issue names no source files or tests, so locate the Table implementation and its coverage first. Done means table cells support vertical alignment and the documented behavior is verified.
