+### Using Reactive Data
+
+> **New in v8.20.0**
+
+The `useVueTable` hook now supports reactive data. This means you can pass a Vue `ref` or `computed` containing your data to the `data`-option. The table will automatically react to changes in the data.
+
+```ts
+const columns = [
+  { accessor: 'id', Header: 'ID' },
+  { accessor: 'name', Header: 'Name' }
+]
+
+const dataRef = ref([
+  { id: 1, name: 'John' },
+  { id: 2, name: 'Jane' }
+])
+
+const table = useVueTable({
+  columns,
+  data: dataRef, // Pass the reactive data ref
+})
+
+// Later, updating dataRef will automatically update the table
+dataRef.value = [
+  { id: 1, name: 'John' },
+  { id: 2, name: 'Jane' },
+  { id: 3, name: 'Doe' }
+]
+```
+
 ### Custom Initial State
 
 If all you need to do for certain states is customize their initial default values, you still do not need to manage any of the state yourself. You can simply set values in the `initialState` option of the table instance.
