I'm currently writing a report where I have a table stating certain parameter values and their errors. Obviously I want the report to look nice, but since the errors of certain parameters vary by orders of magnitude, I'm not sure how to write it.

It currently looks like:

How should I be writing the errors and parameters?

+1 user37826, that is my answer. I understand you are showing the +/- in the superscript and subscript, respectively, but I don't like this format at all; for one it doesn't give the confidence level being quoted. 90%? 95%? 99.9%? is that a 3-sigma or 5-sigma result?

If I were your advisor I'd tell you to stop trying to save space or be "efficient" and spell it out, every time.

79.5 error of [-2.0, +2.0] at 95% confidence.

If you want to put those in a table, fine, but do one parameter per line. Stop trying to cram your results into a tiny space; the first rule of academic writing is clarity, and you are creating unnecessary confusion. And, as user37826 says, follow the style guide, or lacking that, previous publications in a respected journal. The presentation there is likely something readers are accustomed to seeing, and therefore achieve the goal of clarity.

You really should look at the style guide relevant to your field.

The APA Manual, for example, has an extensive section on tables and provides multiple examples for all common use cases. The relevant style guides for your field will be availiable in your university library.

Another option is to look at publications in your field and emulate their style. If you are at a point in your academic career where you write your first paper, even if only for a seminar, you must have seen other publications. Consult them.

It is unclear to me what your numbers mean and how they relate to each other, and you don't specify your field or relevant style, so it is impossible to provide a more specific answer to your question.
