This property defines the method of distributing columns within the layout.

  • ColumnPercentages: Each column is assigned a size based on the 'Responsive Sizes' property. This configuration facilitates the creation of a responsive table where each column width adjusts according to the specified percentages, ensuring optimal display on different devices.
  • Flow: Columns are distributed based on their intrinsic size. This method utilizes a flex table layout where the width of each column adapts to its content. The behavior of this distribution can be further customized by using the 'Class' property, allowing for specific styling and responsiveness adjustments.
