React table resize column size

I am using
react-table-v

I was following the tutorial from the following link:

the examples/column-resizing

I want to be able to indicate the default size for some of my columns

For Header: “Paid supplier ₪”,
I would like the size to be width 350

For Header: “VAT Paid supplier ₪”,
I would like the size to be width 50

However all columns are the same size
At the following link you can find how I organize the columns

At the following link you can find my table return code

I am attaching a photo how currently the table looks were all columns are the same size.
