Callout: Removing the tab space does not change the output visually.

Wondering if there can be a scenario that remainingSpace becomes 0 or less.

Good question. I don't think there is a valid scenario since that would mean the user would need to have a lot of columns. For instance, for terminal width of 80, the user would need to create more than 27 columns (27 * 3 > 80) for there to be negative remainingSpace.

It would be good to add some more testing to explicitly try out some odd column headings to ensure there's no breaking conditions. I don't have any in mind, but would like to see if we can test some boundary conditions here.
For example, these paths are not unit tested:

Added more unit tests for various scenarios.
Context
The purpose of this PR is to improve the table formatting on the columns to wrap when the text when it reaches an estimated max column width. The max col width is calculated by excluding the padding and applying the remaining space evenly among the columns. Any columns that are expected to be wider than the others (eg. ID and Description) will given more space than the others
The PR uses the go-pretty library to manage the column text wrapping, and max column width and coloring.
