feature: Alternating background in rendered table rows

Is your feature request related to a problem? Please describe.

I'm loving the plugin overall and the only missing part for me is that table rows are a little hard to visually parse for me

Describe the solution you'd like

I know that adding horizontal lines between rows is not acceptable https://github.com/MeanderingProgrammer/render-markdown.nvim/issues/295 but as an alternative I'd like to propose ability to set alternating background color for the table rows.

I'd be willing to try to implement this feature with minimal guidance where should I look in the code.

Describe alternatives you've considered

currently I'm rendering the markdown in the browser when looking into the tables which is not ideal ;)

Start by locating the code responsible for rendering table rows and the existing configuration or highlight handling for tables. Check how a row's position can determine its background and identify any relevant tests. Done means users can configure alternating row backgrounds without adding horizontal lines.
