2000 rows x 500 columns
DataGridXL has excellent scroll performance. The grid has its own lightweight virtual DOM implementation. It means that the grid does not actually have a million DOM nodes in memory. Only the columns are DOM nodes.
This approach is radically different from other products out there. Many other products will show you a "speedy" demo with a million rows. Easy when rows only have a few columns. But DataGridXL is the only product that keeps scrolling smooth with hundreds of columns.
Code
<style>
#grid {
height: 400px;
}
</style>
<div id="grid"></div>
<script src="https://code.datagridxl.com/datagridxl.js"></script>
<script>
var grid = new DataGridXL("grid", {
data: DataGridXL.createDummyData(2000,500),
includeOuterBorder:true
});
</script>
