将带Rowspan/Colspan的JavaScript表格转换为矩阵的技术问题

Hey everyone,

I’ve been building a feature that’s a huge help for web developers working with complex table structures: converting HTML tables that use rowspan and colspan into a matrix format. This makes handling those tricky cross-row and cross-column properties way more manageable programmatically.

The algorithm I’ve put together works reliably for most common scenarios, but I’ve run into some edge cases where it falls short. My core goal is to get the converted table to render exactly like the original one—right now, there are still inconsistencies between the source table and the output matrix-based table that I’m struggling to fix.

For context: In my test setup, the lower converted table doesn’t match the rendering of the upper original table. I’m trying to iron out these discrepancies so both look identical when rendered in the browser.
