How to keep table expandable by inserting table row in a protected worksheet in Excel?

Author Siluvia Last modified

In Excel, when you protect a worksheet, the auto-expanding functionality of tables is often disabled. For example, if you have a table named Table1 and you try to add data under the last row in a protected worksheet, the table will not automatically expand to include the new row. However, there is a way to keep your table expandable even in a protected worksheet. This tutorial will guide you through the steps to enable auto-expansion of your table while the worksheet remains protected.

As below screenshot shown, a table named Table1 in your worksheet, and the last column of the table is a formula column. Now you need to protect the worksheet to prevent the formula column from changing, but allow to expand the table by inserting new row and assign new data into the new cells. Please do as follows.

1. Click Developer > Insert > Button (Form Control) to insert a Form Control button into your worksheet.

VBA code: Keep table expandable by inserting table row in a protected worksheet

'Update by ExtendOffice 20220826
    Dim xRg, tableRg As Range
    Dim xRowCount As Integer
    Dim pswStr As String
    pswStr = "123"
    On Error Resume Next
    Application.ScreenUpdating = False
    ActiveSheet.Unprotect Password:=pswStr

    Set tableRg = ActiveSheet.ListObjects("Table4").Range
    xRowCount = tableRg.Rows.Count
    
    Set xRg = Range("Table4[[#Headers],[Total]]").Offset(1, 0)
    Set yRg = xRg.Resize(xRowCount, 1)
    xRg.Resize(xRowCount - 1, 1).AutoFill Destination:=yRg, Type:=xlFillDefault

    ActiveSheet.Protect Password:=pswStr, DrawingObjects:=False, _
                    Contents:=True, Scenarios:=False, _
                    AllowFormattingCells:=True, AllowFormattingColumns:=True, _
                    AllowFormattingRows:=True, AllowInsertingColumns:=True, _
                    AllowInsertingRows:=True, AllowInsertingHyperlinks:=True, _
                    AllowDeletingColumns:=True, AllowDeletingRows:=True, _
                    AllowSorting:=True, AllowFiltering:=True, _
                    AllowUsingPivotTables:=True
    Application.ScreenUpdating = True

Notes:

1) In the code, number “123” is the password you will use to protect the worksheet.
2) Please change the table name and the name of the column that contains the formula you will protect.

4. Press the Alt + Q keys to close the Microsoft Visual Basic for Applications window.

5. Select the cells in the table you need to assign new data into except the formula column, then press the Ctrl + 1 keys to open the Format Cells dialog box. In the Format Cells dialog box, uncheck the Locked box, and then click the OK button. See screenshot:

6. Now protect your worksheet with the password you have specified in the VBA code.

From now on, after clicking the Form Control button in your protected worksheet, the table will be expandable by inserting new row as below screenshot shown.

Note: you can modify the table except the formula column in the protected worksheet.
