[vba] Add new row to excel Table (VBA)

As using ListRow.Add can be a huge bottle neck, we should only use it if it can’t be avoided. If performance is important to you, use this function here to resize the table, which is quite faster than adding rows the recommended way.

Be aware that this will overwrite data below your table if there is any!

This function is based on the accepted answer of Chris Neilsen

Public Sub AddRowToTable(ByRef tableName As String, ByRef data As Variant)
    Dim tableLO As ListObject
    Dim tableRange As Range
    Dim newRow As Range

    Set tableLO = Range(tableName).ListObject
    tableLO.AutoFilter.ShowAllData

    If (tableLO.ListRows.Count = 0) Then
        Set newRow = tableLO.ListRows.Add(AlwaysInsert:=True).Range
    Else
        Set tableRange = tableLO.Range
        tableLO.Resize tableRange.Resize(tableRange.Rows.Count + 1, tableRange.Columns.Count)
        Set newRow = tableLO.ListRows(tableLO.ListRows.Count).Range
    End If

    If TypeName(data) = "Range" Then
        newRow = data.Value
    Else
        newRow = data
    End If
End Sub
