>>351 そんなことするなら素直に >セルごとに隣接判定をして罫線を描く/描かないの処理 を実装すればいいんじゃねえかと Sub test() Dim r As Range Dim r2 As Range Set r2 = Selection For Each r In Selection If Not isSelect(r, xlEdgeTop) Then r.Borders(xlEdgeTop).LineStyle = xlContinuous If Not isSelect(r, xlEdgeBottom) Then r.Borders(xlEdgeBottom).LineStyle = xlContinuous If Not isSelect(r, xlEdgeLeft) Then r.Borders(xlEdgeLeft).LineStyle = xlContinuous If Not isSelect(r, xlEdgeRight) Then r.Borders(xlEdgeRight).LineStyle = xlContinuous Next End Sub Function isSelect(testRange As Range, index As XlBordersIndex) As Boolean On Error Resume Next Dim r As Range For Each r In Selection Select Case index Case xlEdgeTop If r.Address = testRange.Offset(-1, 0).Address Then isSelect = True Case xlEdgeBottom If r.Address = testRange.Offset(1, 0).Address Then isSelect = True Case xlEdgeLeft If r.Address = testRange.Offset(0, -1).Address Then isSelect = True Case xlEdgeRight If r.Address = testRange.Offset(0, 1).Address Then isSelect = True End Select Next End Function こんな感じか。行数制限あるからやってるけど、1行If は推奨しないぞ
