Build one like it

The smallest complete version, in each language CanopyX supports for this view. The demo above is the same API with more data.

using CanopyX;
using CanopyX.Html;

var layers = new CanopyDataGridView("settings", "Where the setting comes from") {
    Stack = new CanopyStack()
};
layers.Columns.Add(new CanopyColumn("title", "Layer") { RowHeader = true });
layers.Columns.Add(new CanopyColumn("value", "Value"));
foreach (var (id, title, value) in new[] {
    ("defaults", "Shared defaults", "Standard"),
    ("site", "Site policy", "Extended"),
    ("user", "User preference", "Compact")
}) {
    var row = new CanopyGridRow(id);
    row.Cells["title"] = title;
    row.Cells["value"] = value;
    layers.Rows.Add(row);
}

layers.Stack.Layers.Add(new CanopyStackLayer(
    "defaults", "defaults", "The starting value."));
layers.Stack.Layers.Add(new CanopyStackLayer(
    "site", "site", "Enforced by policy, but a user may narrow it.") {
    Enforced = true
});
layers.Stack.Layers.Add(new CanopyStackLayer(
    "user", "user", "The value this session uses.") {
    Winner = true
});
layers.SaveHtmlPage("stack.html");
