+- Plugin Hook
+- Optional
+
+`useResizeColumns` is a plugin hook that adds support for resizing headers and cells when using non-table elements for layout eg. the `useBlockLayout` and `useAbsoluteLayout` hooks. It even supports resizing column groups!
+
+### Table Options
+
+- `disableResizing: Bool`
+  - Defaults to `false`
+  - When set to `true`, resizing is disabled across the entire table
+
+### Column Options
+
+The core column options `width`, `minWidth` and `maxWidth` are used to calculate column and cell widths and must be set. [See Column Options](#column-options) for more information on these options.
+
+- `disableResizing: Bool`
+  - Defaults to `false`
+  - When set to `true`, resizing is disabled for this column
+
+### Header Properties
+
+- `getResizerProps`
+  - **Usage Required**
+  - This core prop getter is required to to enable absolute layout for headers
+- `canResize: Bool`
+  - Will be `true` if this column can be resized
+- `isResizing: Bool`
