I have a two-dimensional array. after editing the content, can I save it as a new two-dimensional number for the row?

I have A two-dimensional array. I want to edit the content and save it as A new two-dimensional number for the row. Do I read A two-dimensional array A from the cache, display the values of the two-dimensional array in A list table, and modify the value of the list by clicking save to overwrite the original array A. can this effect be achieved ??, My sweat... what is your cache carrier ?, What do you want to do after exploring the carrier text file?
