How to safelist all flex columns

[syntaxlexx]

Hi there.
I am trying to safelist all flex and width properties by deffault. So far I have the following in the tailwind.config.js

{
            pattern: /flex-(wrap|col|row)-(1|2|3|4|5|6|7|8|9|10|11|12)/,
            variants: ["lg", "md"],
        },
        {
            pattern: /w-(1|2|3|4|5|6|7|8|9|10|11|12)-(1|2|3|4|5|6|7|8|9|10|11|12)/,
            variants: ["lg", "md"],
        },

The compiler throws some warnings ont he above. How can I go about this? TY
