Multi-Level Headers

Configuration

StkTableColumn['children'] configures multi-level headers

const columns: StkTableColumn<any>[] = [
    {
        dataIndex: 'Basic',
        title: 'Basic',
        children: [ 
            { dataIndex: 'id',title: 'ID', width: 100,},
            {
                dataIndex: 'lv2',
                title: 'Lv 2',
                width: 100,
                children: [ 
                    { dataIndex: 'lv2_1', title: 'Lv 2.1', width: 100,}, 
                    { dataIndex: 'lv2_2', title: 'Lv 2.2', width: 100,},
                ],
            },
        ],
    },

Horizontal Virtual List

With the help of AI, multi-level headers finally support horizontal virtual list!

Configure props.virtualX to enable it.

TIP

If a parent header has many child nodes, try splitting the headers for better virtual scrolling performance.

Column Fixing

Most Common Column Fixing

TIP

The fixed column value in multi-header tables only affects the current header node. If you want to fix parent headers, you also need to configure fixed.

const columns: StkTableColumn<any>[] = [
    {
        dataIndex: 'Basic',
        title: 'Basic',
        fixed: 'left', 
        children: [
            { 
                dataIndex: 'id',
                title: 'ID',
                width: 100,
                fixed: 'left'
             },
            {
                dataIndex: 'lv2',
                title: 'Lv 2',
                width: 100,
                fixed: 'left', 
                children: [
                    { 
                        dataIndex: 'lv2_1',
                        title: 'Lv 2.1', 
                        width: 100, 
                        fixed: 'left'
                    }, 
                    { 
                        dataIndex: 'lv2_2',
                        title: 'Lv 2.2', 
                        width: 100, 
                        fixed: 'left'
                    }, 
                ],
            },
        ],

Isn't that interesting? This is also thanks to the sticky feature.
