Numeric only cells drop leading 0

This is a huge problem with most CSV editing tools, even Microsoft Excel. I often am dealing with large CSV files that have a number of entries consisting of numbers that must retain a leading 0 digit. I understand why it does this from a programming point of view, but it's very frustrating.

No source files, tests, or entry points are identified in the issue. Reproduce the behavior in TableTool with CSV values containing leading zeros, then trace the cell import or value-conversion path; done means those leading zeros remain visible after opening and editing the CSV.
