At one time tables were one of the only ways to offer navigation in a website that was designed into several separate areas. This has changed with the use of Cascading Style Sheets (CSS) and, when used correctly, these provide a better structure that is easier to navigate.
It is possible to check the code and look out for examples of table elements and attributes e.g. TR, TD, TH and CAPTION or to use the Web Developer toolbar which can show borders around the tables and if you select the issues that occur on the W3C example of an inaccessible webpage you will see the tables that fail with explanations

WCAG 2.0: Guideline 1.3 Adaptable: Create content that can be presented in different ways (for example simpler layout) without losing information or structure. Understanding Guideline 1.3
1.3.1 Info and Relationships: Information, structure, and relationships conveyed through presentation can be programmatically determined or are available in text. (Level A) How to Meet 1.3.1 | Understanding 1.3.1
1.3.2 Meaningful Sequence: When the sequence in which content is presented affects its meaning, a correct reading sequence can be programmatically determined. (Level A) How to Meet 1.3.2 | Understanding 1.3.2
3.2.3 Consistent Navigation: Navigational mechanisms that are repeated on multiple Web pages within a set of Web pages occur in the same relative order each time they are repeated, unless a change is initiated by the user. (Level AA) How to Meet 3.2.3 | Understanding 3.2.3
