JavaScript DataGrid (Vue)

FlexGrid is a fast, flexible and familiar JavaScript DataGrid. Our core grid module includes all of the most common features. We also include extensions and a flexbile API to customize to grid even further.

This sample shows off many features of FlexGridincluding sorting, grouping, searching, Excel-like filtering, DataMaps, custom CellTemplates, sparklines, rich editing, Excel/PDF export, validation, DetailRows, and more.

Try changing the number of data items and notice how the grid remains fast, even with very large datasets. FlexGrid achieves this level of performance by automatically virtualizing rows and columns.
