+# `DisplayTable` Component Specification
+
+## Overview
+
+A `DisplayTable` is used for presenting information displayed across columns and rows.
+
+---
+
+## Design
+
+`DisplayTable` is only for presentational concerns. It doesn't support advanced capabilities such as selection, sorting, and row expansion. With that in mind, complexities are primarily shifted to surfacing a simple component API, structuring the table properly to support the style requirements, and ensuring that accessibility markup is applied correctly.
+
+Even though `DisplayTable` doesn't do much in terms of functionality, because accessibility concerns can be non-trivial, we will use `useTable` from React Aria to ensure that we have our accessibility bases covered.
+
+### API
+
+```ts
+
+```
+
+### Example Usage
+
+_Simple_:
+
+```tsx
+import { Modal } from "@easypost/easy-ui/Modal";
+
+function PageWithModal() {
+  return <DisplayTable />;
+}
+```
