Recently, I have been analyzing student data and noticed a recurring structure. While preparing to present information on student performance within the discipline, I also became interested in showcasing a history of new students. It was suggested that having a table containing tables would be beneficial. After considering different options, I came across a structure that is illustrated in the images below.

I recall using a similar feature in Syncfusion when working as a .NET programmer. However, I have not found suitable JavaScript plugins to achieve this desired outcome. Does anyone have suggestions for implementing this with just JavaScript and CSS?
