prime ng table performance issue on more than 100 columns

Question

I use prime ng table, p-table, to display large amounts of data. lets say 20k rows and 500 columns.

I use virual scroll for the rows to render dynamically.

The table is smooth when there are 20k rows and 20 columns.

But when the number of columns increases the table lags significantly that sometimes it kills the browser.

What is the common practice to handle large number of columns to have better performance?

I clarify that even with 300 rows and 150 columns its slow.

Thanks
