Vue.js is a front-end JavaScript framework whose core library focuses on the view layer. At the same time, it is also a progressive framework for building user interfaces that can be mixed with other libraries or existing projects. Vue.js separates the application's runtime state from the visual representation of the state, helping developers manage and update the UI more easily.

In this article, we will introduce the Vue.js component and its application in creating dynamic tables.

Vue.js components are reusable, self-contained blocks of code that can be used to express a single feature, element, or area of an application. In Vue.js, the concept of components is embodied in Vue instances, where each instance is a component. Think of a component as a custom element that contains its own options and lifecycle methods.

In order to create a Vue.js component, you can use the Vue.component() method, which receives two parameters. The first parameter is the name of the component, and the second parameter is the component object, which contains the element's HTML template, computed properties, methods, and other options.

In the example below, we will create a Vue.js component called "dynamic-table" that will render a dynamic table:

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <title>动态表格</title>
    <script src="https://cdn.jsdelivr.net/npm/vue/dist/vue.js"></script>
</head>
<body>
    <div id="app">
        <dynamic-table></dynamic-table>
    </div>

    <script>
        Vue.component('dynamic-table', {
            data: function() {
                return {
                    tableData: [
                        { id: 1, name: '张三', age: 20 },
                        { id: 2, name: '李四', age: 25 },
                        { id: 3, name: '王五', age: 30 },
                        { id: 4, name: '赵六', age: 35 }
                    ],
                    headings: ['编号', '姓名', '年龄']
                }
            },
            template: `
                <table>
                    <thead>
                        <tr>
                            <th v-for="heading in headings">{{ heading }}</th>
                        </tr>
                    </thead>
                    <tbody>
                        <tr v-for="data in tableData">
                            <td>{{ data.id }}</td>
                            <td>{{ data.name }}</td>
                            <td>{{ data.age }}</td>
                        </tr>
                    </tbody>
                </table>
            `
        })

        var app = new Vue({
            el: '#app'
        })
    </script>
</body>
</html>

In this example, we use The Vue.component() method creates a component named "dynamic-table". In the data attribute of the component, we define the data (tableData) and headers (headings) of the dynamic table. We use Vue's template syntax to define the HTML template of the table in the template attribute, and use the v-for directive to generate dynamic table rows and columns.

When the component is rendered, we use the component registered with the Vue.component() method in the Vue instance so that it can be used on the page. If you want to use the "dynamic-table" component on the page, you only need to use the custom element of the dynamic table, that is, <dynamic-table></dynamic-table>.

Through the above examples, we learned how to use Vue.js components to create basic dynamic tables. In actual projects, more complex table functions can be implemented by defining more calculated properties, methods, and events. With the help of Vue.js, creating dynamic tables becomes easier and more convenient.
