Welcome to the community Doug!
Hard to determine exactly what you need from the info provided, but it sounds like you just want to make 52 columns, Number Columns to be exact, and then name them the week # or the date range? You want to enter number of hours each week per line item right?
So if you are on the board, find the black and white “+” button on the far right and choose “Numbers”, then format the column how you like. Then you can either duplicate it or keep hitting + to add more numbers columns. Add 52, name them and then you are all set.
Hope this helps! Let me know if you need more info.
