[Feature Request] Expand table / Collapse table

**Is your feature request related to a problem? Please describe.**
If you have a markdown table they will might reach the limit if you are using the "Navigation" on the left side and "In this article" on the right side.
E.g. as shown here: https://dotnet.github.io/docfx/docs/markdown.html?tabs=linux%2Cdotnet#settings

**Describe the solution you'd like**
Microsoft is using in their documentation a "Expand table"-feature to expand the table to the full width of the website in a layover. As shown in this example: https://learn.microsoft.com/en-us/azure/role-based-access-control/role-definitions#what-tools-support-using-azure-roles-for-data-actions
