React Tree Grid 다중 컬럼 헤더 개요

    The Ignite UI for React Multi-Column Headers feature in React Tree Grid allows you to group columns by placing them under a common multi-header. Each multi-column headers group in the IgrTreeGrid could be a representation of combinations between other groups or columns. This feature is particularly useful when dealing with large datasets where scrolling horizontally might be cumbersome.

    React Tree Grid Multi-Column Headers Example

    The declaration of multi-column headers is achieved by wrapping a set of columns into an columnGroup component with header title information passed.

    <IgrTreeGrid primaryKey="ID" foreignKey="ParentID">
    <IgrColumnGroup header="Contact Information">
        <IgrColumn sortable={true} resizable={true} field="Phone" dataType="string"></IgrColumn>
        <IgrColumn sortable={true} resizable={true} field="Fax" dataType="string"></IgrColumn>
        <IgrColumn sortable={true} resizable={true} field="PostalCode" dataType="string"></IgrColumn>
    </IgrColumnGroup>
</IgrTreeGrid>

    중첩 헤더 수준을 달성n-th 하려면 위의 선언을 따라야 합니다. 그래서 중첩이columnGroup 원하는 결과를 낳는다.

    <IgrTreeGrid primaryKey="ID" foreignKey="ParentID" moving={true}>
    <IgrColumnGroup pinned={false} header="General Information">
        <IgrColumn field="HireDate" sortable={true} resizable={true} dataType="date"></IgrColumn>
        <IgrColumnGroup header="Person Details">
            <IgrColumn field="ID" resizable={true} filterable={true} dataType="number"></IgrColumn>
            <IgrColumn field="Title" sortable={true} resizable={true} dataType="string"></IgrColumn>
            <IgrColumn field="Age" sortable={true} resizable={true} dataType="number"></IgrColumn>
        </IgrColumnGroup>
    </IgrColumnGroup>
</IgrTreeGrid>

    Every columnGroup supports moving, pinning and hiding.

    [!Note] When there is a set of columns and column groups, pinning works only for top level column parents. More specifically pinning per nested column groups or columns is not allowed.
    Moving between columns and column groups is allowed only when they are at the same level in the hierarchy and both are in the same group.
    When columns/column-groups are not wrapped by current group which means they are top level columns, moving is allowed between whole visible columns.

    <IgrTreeGrid primaryKey="ID" foreignKey="ParentID" moving={true}>
    <IgrColumnGroup header="Contact Information">
        <IgrColumn field="Phone" movable={true} sortable={true} resizable={true} dataType="string"></IgrColumn>
    </IgrColumnGroup>
    <IgrColumn field="Name" sortable={true} resizable={true} dataType="string"></IgrColumn>
    <IgrColumn field="Title" sortable={true} resizable={true} dataType="string"></IgrColumn>
    <IgrColumn field="Age" sortable={true} resizable={true} dataType="number"></IgrColumn>
</IgrTreeGrid>

    Multi-Column Header Template

    <IgrColumnGroup header="Contact Information" headerTemplate={groupHeaderTemplate}></IgrColumnGroup>

    const groupHeaderTemplate = (e: IgrColumnTemplateContext) => {
  const column = e.column as IgrColumnGroup;
  return (
    <div>
      <span style={{ float: "left" }}>{column.header.toUpperCase()}</span>
    </div>
  );
}

    [!Note] If a header is re-templated and the corresponding column group is movable, you have to set the draggable attribute to false on the templated elements, so that you can handle any of the events that are applied!

    const columnHeaderTemplate = (e: IgrColumnTemplateContext ) => {
  const column = e.column as IgrColumnGroup;
  return (
    <span onClick={onClick}>
      <IgrIcon data-draggable="false"></IgrIcon>
    </span>
  );
}

    다음 샘플은 헤더 템플릿을 사용하여 축소 가능한 열 그룹을 구현하는 방법을 보여줍니다.

    Styling

    사전 정의된 테마 외에도 사용 가능한 CSS 속성 중 일부를 설정하여 그리드를 추가로 사용자 정의할 수 있습니다. 일부 색상을 변경하려면 먼저 그리드에 대한 클래스를 설정해야 합니다.

    <IgrTreeGrid className="grid"></IgrTreeGrid>

    그런 다음 관련 CSS 속성을 이 클래스로 설정합니다.

    .grid {
    --ig-grid-header-background: #e0f3ff;
    --ig-grid-header-text-color: #e41c77;
    --ig-grid-header-border-width: 1px;
    --ig-grid-header-border-style: solid;
    --ig-grid-header-border-color: rgba(0, 0, 0, 0.08);
}
