Accessibility issues

Issue Type (delete the irrelevant ones)

Enhancement Request

Specs

version 2.21.0

What browser?
Chrome 84.0.4147.135

Expected Behavior

Tables should meet WCAG accessibility guidelines. Search should have an accessible name; e.g., a label; column headers/sort "buttons" should be keyboard accessible; elements should have sufficient color contrast

Actual Behavior

Sort is not accessible for keyboard/screen reader users; Search is missing a label; several elements fail WCAG color contrast requirements.

Steps to Reproduce the Problem

Run vue-good-table through Axe, ARC Toolkit and similar accessibility testing tools. Or try using a screenreader, such as VoiceOver, to sort tables.

[EDIT]
I've submitted PR #752 to resolve (some of) these issues.
