Detailed introduction about Sheet page

This article mainly introduces the method of Java exporting Excel reports based on templates and copying the templates to generate multiple Sheet pages, which has a good reference value. Let's take a look at it with the editor. Because there are a lot of report exports recently, we have put it into a tool class. The usage scenario of this tool class is to export Excel reports based on the provided template and copy them based on the provided template Sheet page. In order to realize the needs of multiple Sheet pages, when using this tool class, if the demand is that the data in each Sheet page is inconsistent, but the table style and template are the same, then you only need to query the data to be added based on SQL in the actual situation. The technology used in the source (just change the data source) is POI export. Because of the class, it currently only supports the 2003 version of Excel. Please download the corresponding jar package before use! If I have time later, I will further improve it. This is my first time writing a tool class. Please forgive me if there are any imperfections! First look at the template style and running results, and then go directly to the code. This is the template style of Excel. This is the export result. For specific implementation, see demopackage com.sgcc

Looking for a solution to the excessive memory usage when phpexcel processes large files. This How to deal with

Introduction: Looking for a solution to the excessive memory usage when phpexcel processes large files. Due to the memory processing mechanism of phpexcel, when the number of rows or columns of the excel file is too large, it will occupy too much space. The memory will be hundreds of MB in an instant. Due to server reasons, I cannot apply for more memory, so I can only try to fundamentally solve or avoid the problem. For example, after processing an excel file or one of the sheet pages, release the memory and then process the next one. , I have searched around on the Internet, but no one has written it in detail and complete. I ask God to help me adjust it. I am very much looking forward to it.
