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

plotly.graph_objects.Table とリンク先の Plotly table documentation から始め、既存の水平配置の動作と要求されている垂直配置オプションを理解します。issue では source files や tests が指定されていないため、まず Table implementation とその coverage を見つけます。完了条件は、table cells が垂直配置をサポートし、documented behavior が検証されていることです。
