There have been extensive discussions about all uppercase letters in tables such as this one

In SOLIDWORKS 2018, you can select cells to switch them to all upper cases as shown below to comply with standards better.

ASME Y14.5 stated: “Notes herein in capital letters are intended to appear on finished drawings. Notes in lowercase letters are explanatory only and are not intended to appear on drawings.” Right now, custom property values and system values are linked to tables as case sensitive.
