How to nest Grid tables and bind data in Vue.js

Vue.js is a popular front-end framework with good performance and maintainability. Vue.js provides many powerful features, one of which is Grid. Grid table is a very important function in Vue.js, which can be used to display and edit data. However, in actual development, it is often necessary to use the nesting of Grid tables, that is, to use one Grid table as a subcomponent of another Grid table. So, how to nest Grid tables and bind data in Vue.js?

It is very easy to nest Grid tables in Vue.js. You only need to use components to achieve it. The components of Vue.js are reusable and very flexible, so the Grid table can be regarded as a component, and then another Grid table component can be nested within it. The following is a simple example of a nested Grid table in Vue.js:

<template>
  <div>
    <h2>Parent Grid Table</h2>
    <grid-table :columns="columns" :data="parentRows"></grid-table>
    <h2>Child Grid Table</h2>
    <grid-table :columns="childColumns" :data="childRows"></grid-table>
  </div>
</template>

<script>
import GridTable from './GridTable.vue'

export default {
  components: {
    GridTable
  },
  data () {
    return {
      columns: [
        {
          name: 'id',
          label: 'ID'
        },
        {
          name: 'name',
          label: 'Name'
        },
        {
          name: 'email',
          label: 'Email'
        }
      ],
      parentRows: [
        {
          id: 1,
          name: 'John',
          email: 'john@example.com'
        },
        {
          id: 2,
          name: 'Jane',
          email: 'jane@example.com'
        }
      ],
      childColumns: [
        {
          name: 'id',
          label: 'ID'
        },
        {
          name: 'product',
          label: 'Product'
        },
        {
          name: 'price',
          label: 'Price'
        }
      ],
      childRows: [
        {
          id: 1,
          product: 'Apple',
          price: 1.00
        },
        {
          id: 2,
          product: 'Banana',
          price: 1.50
        },
        {
          id: 3,
          product: 'Orange',
          price: 1.25
        }
      ]
    }
  }
}
</script>

In this example, we first define two Grid table components, one is the parent component and the other is the child component. The data of the parent component includes three properties: columns (column definitions of the table), parentRows (row data of the table), and the definition of a child component. The data of the child component similarly includes three attributes: childColumns (column definition of the subtable), childRows (row data of the subtable).

In the parent component, we use the component twice and pass data through attributes. In the child component, we define two properties: data and columns. In the child component, the data attribute value comes from the childRows data of the parent component, and the columns attribute value comes from the childColumns attribute defined by the child component.

In this way, we can implement nested Grid tables and bind data to each table. In actual development, similar methods can be used to handle complex UI layout and data binding requirements.

To sum up, nested Grid tables in Vue.js are a very common and necessary technology that can help us achieve complex UI layout and data binding requirements. The componentization and data binding mechanism of Vue.js makes it very easy to implement nested Grid tables. Developers only need to write code according to the syntax rules of Vue.js.
