ColumnVirtualizationConfig

Configuration for horizontal (column) virtualization.

When enabled, only the columns visible in the viewport (plus an overscan buffer) are rendered to the DOM. This dramatically improves performance for grids with many columns (50+), as only a small subset of column cells exist at any time.

By default, virtualization auto-enables when the column count exceeds threshold. Set autoEnable: false to control activation manually.

Example

new ColumnVirtualizationPlugin({
  threshold: 20,   // activate earlier than default
  overscan: 5,     // render 5 extra columns on each side
})

Properties

Property	Type	Description
autoEnable?	boolean	Auto-enable when column count exceeds threshold (default: true)
threshold?	number	Column count threshold for auto-enabling (default: 30)
overscan?	number	Extra columns to render on each side for smooth scrolling (default: 3)
