This article shows you how to achieve consecutive serial numbers of different grouped data on web pages. The content is concise and easy to understand, which can definitely brighten your eyes. I hope you can get something through the detailed introduction of this article.

If there is no report tool, it can be realized through the front-end code, which is mainly divided into two parts: the first part is to add the serial number setting after sorting the data, and the second part merges the column data corresponding to the grouped fields with the same value. However, when the data has paging or hidden rows, the code processing complexity will be high, and when the amount of data is relatively large, the performance processing requirements for developers are relatively high.

If there is a report tool, an expression can easily achieve the requirement of serial number. Moistening the report provides a variety of serial number generation methods, such as:

The sequential sequence numbers of different grouped data can be realized through the seq () function:

In addition, you can also use & Cell to achieve the group serial number, row () to obtain the line number and other ways to achieve the serial number. In the case of hidden rows, the dry report provides the concept of a temporary variable, which is sequentially numbered through a simple expression: if (condition, variable a, variable a = variable axi1). For the specific settings of various serial number requirements, please refer to: data report a variety of serial number generation methods

The above is how the web page implements the serial numbers of different grouped data. Have you learned the knowledge or skills? If you want to learn more skills or enrich your knowledge reserve, you are welcome to follow the industry information channel.
