It depends. “Open Access” refers to material (typically journal articles) that is freely available online, but it is not necessarily freely reusable. For Creative Commons-licensed material, it depends on the license type. Licenses such as CC BY, CC BY 3.0, CC BY 4.0 are examples of licenses that permit such use. If you are reusing figures or tables published under these licenses, you will not require permission although it is important to acknowledge the source as specified in the publisher’s terms. On the other hand, material available under a Creative Commons Attribution-Non-Commercial-No Derivatives (CC BY-NC-ND) license would require permission to include in your Elsevier book chapter, since Elsevier is a commercial publisher.
