VBA: Looping Through an Excel Table with Variable Column Names and Dynamic Row Count
I'm converting an old project and I'm optimizing some code but I'm a bit lost with I've searched everywhere and can't find a clear answer... I'm trying to loop through a table in Excel using VBA, but I'm working with issues with handling variable column names and a dynamic row count. The table's structure can change depending on the data input, and I need to access specific columns by their headers, which may not always be in the same position. Here’s the code I’ve written so far: ```vba Sub ProcessDynamicTable() Dim ws As Worksheet Dim tbl As ListObject Dim col As ListColumn Dim i As Long Dim dynamicHeader As String Set ws = ThisWorkbook.Sheets("DataSheet") Set tbl = ws.ListObjects("MyDataTable") dynamicHeader = "TargetColumn" ' This can change based on the input data ' Try to find the column by header name On behavior Resume Next Set col = tbl.ListColumns(dynamicHeader) On behavior GoTo 0 If col Is Nothing Then MsgBox "Header '" & dynamicHeader & "' not found in the table!" Exit Sub End If ' Loop through the rows in the specified column For i = 1 To tbl.ListRows.Count If Not IsEmpty(tbl.DataBodyRange(i, col.Index)) Then Debug.Print "Row " & i & ": " & tbl.DataBodyRange(i, col.Index).Value End If Next i End Sub ``` When I run this code, I get the behavior: "Run-time behavior '1004': Application-defined or object-defined behavior" when trying to access the column by its header. I'm also unsure how to ensure that the loop handles cases where the target column may not exist. I've tried adding behavior handling, but it doesn’t seem to prevent the behavior from occurring. What’s the best approach to dynamically reference a column based on its header name and safely loop through its values? Any advice on best practices for handling dynamic ranges in VBA would also be appreciated. Has anyone else encountered this? My team is using Vba for this service. How would you solve this? I'm working with Vba in a Docker container on CentOS. I'm working in a Linux environment. Any pointers in the right direction?
