I would like to delete the source column for a formula in Numbers 3.2.2, without destroying values in the formula's output column. Specifically, I have a column of "Last, First" names, which I parse by comma and output to two separate columns, "Last" and "First". How can I delete the "Last, First" column without destroying the output values in the "Last" and "First" columns?
An image of the current state of things is shown in the link after this paragraph. The formula used to generate the First Name column is shown for the "Example, A" entry. I'd like to lock the output column's values in place, such that they no longer draw on the source column, "Full Name".
