There are two methods for ImportCustomObjects the first one takes in
ImportTableOptions that will tell the spreadsheet which columns are formulas.
public int ImportCustomObjects(ICollection list, int firstRow, int firstColumn, ImportTableOptions options;
How do I implement that for the second method that doesn’t take ImportTableOptions as a parameter?
public int ImportCustomObjects(ICollection list, string[] propertyNames, bool isPropertyNameShown, int firstRow, int firstColumn, int rowNumber, bool insertRows, string dateFormatString, bool convertStringToNumber);
how do I tell the method which columns are formulas?
