HTML datatable with some dynamic columns and some fixed columns

I use Flask backend and HTML frontend. I need HTML code that creates a Bootstrap table with dynamic columns depending on the number of columns in the input data received from server. Sometime the input data will have 2 columns, at other time it may have 5 columns. Accordingly the HTML table should show 2 or 5 columns. What I need is that the HTML table column (header and data) should change accordingly. There are a few columns that will always be fixed. My budget for this work is $10.
