LabelSpan プロパティ

ラベル(列ヘッダー)に割り当てられるSpanX部分またはSpanY部分を指定します。LablePositionがLeftまたはRightに設定されている場合はラベルのSpanX部分を指定し、TopまたはBottomに設定されている場合はラベルのSpanY部分を指定します。LabelPositionがNoneに設定されている場合(列ラベルがセルと共に表示されない場合)、このプロパティは無視されます。LabelPositionが LabelOnly に設定されている場合(セルが表示されない場合)にも、このプロパティは無視され、SpanX および SpanY 全体がラベルに使用されます。デフォルト値は 1 です。
