Is there a faster code for adding a new row to a table – Excel VBA

Posted by: admin April 23, 2020 Leave a comment


I add a new row to a table, everytime my code finds a new value to add to it.
The code I use for this Set newRow = ProjectTable.ListRows.Add works fine.
but this makes it run very slow.

Is there a code that accomplishes the same but runs quicker?

Dim ProjectName As String
Dim ResourceType As String
Dim newRow As ListRow
Dim RPLastRow As Long
RPLastRow = RPSheet.Cells(Rows.Count, 1).End(xlUp).Row

For Each cell In RPSheet.Range("A5:A" & RPLastRow)
    If cell = project Then
        Dim cRow As Long
        cRow = cell.Row

        'enter resource type to table
        ResourceType = RPSheet.Range("B" & cRow).Value
        Set newRow = ProjectTable.ListRows.Add
        newRow.Range(1, 1).Value = ResourceType

        'find amount of resources linked to project and add number to table
        ProjectName = project
        newRow.Range(1, 2).Value = Sheet2.NumberOfResources(ProjectName, ResourceType)
    End If
Next cell

EDIT: Added some extra code so its more clear

The faster way is to add data to the end of the table and then simply resize it.

Here is an example

ProjectTable.Resize Range("$A$1:$E$" & lRow)

Where lRow is the new last row
