Visual Basic：如何在循环遍历 DataTable 行时删除特定列？

Question

I'm looping through the datatable as follows:

For Each row As DataRow In records.Rows
    If row.Item("SYS_CHANGE_OPERATION") = "I" Then

    End If
Next

When the row meets the condition of the column, I need to remove an specific column of that same row.

I know how to do it, if I want to remove a column from the whole DataTable. Code is a simple as:

myDataTable.Columns.Remove("IdKey")

Simple code, yet, I don't find an answer around Google nor SO that explain how to remove a column withing the loop of rows.

Help! Thank you!

Set cells empty:

Dim x = dt.Rows.Cast(Of DataRow).Where(Function(r) r("SYS_CHANGE_OPERATION") = "I")
x.ToList().ForEach(Sub(r) r("SYS_CHANGE_OPERATION") = Nothing)
