Implementing advanced features in a table can significantly improve the usability and efficiency of the data presented. In this post, I am going to detail the steps necessary to perform three specific functions: sorting, filtering, and searching.
ordering: A sort function allows users to sort data in the table based on a specific criterion, such as alphabet, date, or numeric value. To implement this in your table, you can use some JavaScript library like DataTables or implement your own sorting algorithm. Make sure you give the table headers the necessary labels so that users can click and sort the data accordingly.
Filtered out: Filtering allows users to reduce the number of rows displayed in the table based on certain criteria. It can be useful when the table contains a large amount of data and users are only interested in a specific subset. A common way to implement filtering is to add text entry fields or drop-down menus above the table, where users can enter filtering criteria and then update the table to show only rows that meet those criteria.
Search: The search function allows users to quickly find specific data in the table. You can implement a search bar that sits above the table, and as users type in the search bar, the table will update to show only the rows that contain the search terms. You can also add additional options, such as searching only in a specific column or enabling searching by exact or partial match.
Implementing these advanced features in a table can improve the usability of your application and give users more flexibility and control over data display. By following these steps and using the right tools, you can deliver an improved and efficient user experience.
