Vue is a popular JavaScript framework for building interactive, high-performance web applications. In Vue applications, tables are common UI components, and it is often necessary to implement hidden row folding effects to improve user experience. This article will introduce a method to achieve the folding effect of hidden rows in Vue tables.
Implementation steps
- In the template of the Vue component, define the basic structure of the table. Use the v-for directive to traverse the row data of the rendered table from the data source. Among them, you need to add a row bound to the click event to trigger the row folding effect. The code example is as follows:
| 姓名 |
年龄 |
身高 |
| {{item.name}} |
{{item.age}} |
{{item.height}} |
|
- Define variables in the data attribute of the component to determine whether the rows in the table need to be folded. And when initializing the component, set the state of all rows to unfolded. The code example is as follows:
- Define a component that folds rows. The component's template contains content that needs to be collapsed. When a row needs to be folded, the hidden content is rendered. The component code example is as follows:
- In the body of the table, add a tr containing the folded row component. Use the v-if instruction to determine whether the current row needs to be folded. If it is folded, render the folded row component. The code example is as follows:
| 姓名 |
年龄 |
身高 |
| {{item.name}} |
{{item.age}} |
{{item.height}} |
|

- For style processing, you can use CSS to control it. By setting the width and height of .fold to 0, it takes up no space. By setting the styles of .fold:before and .fold:after pseudo-elements, you can switch the fold icon. The code example is as follows:
So far, we have successfully implemented the hidden row folding effect of the Vue table. Through this method, we can easily improve the user experience and make it easier for users to view and manage table data.
