Working with TALL stack - issue with styles

[ItsJustPW]

When I'm working with powergrid, in tailwind.config.js I set:

        require("@tailwindcss/forms")({
            strategy: 'class',
        }),
      ]

However, when I do this, it messes up the spacing on input fields etc through the rest of my site as I need to replace:

plugins: [forms], with the above code.

I followed the instructions to use my own theme to see if I could fix anything that way, but nothing seems to be working and I'm stuck with this two part problem:

plugins: [forms], <-- my site works OK, but the tables don't take on styling

        require("@tailwindcss/forms")({
            strategy: 'class',
        }),
      ]

<-- I loose site styling, the grids seem to take on some styling, but everything else is broke.

Does anyone have any ideas please?
