在VSTO C＃中启动Excel时如何预先建立列宽

Question

我正在尝试在Excel打开之前定义列宽。因此，在执行任何操作之前，我希望具有所需的列宽。我正在将Visual Studio Tools for Office与ThisAddIn类（功能区）一起使用。在下面，我提供了要在其中实现此功能的类。有很多答案与我的问题相似，但不完全相同。

namespace CreateLayout 
{
    using System;
    using Excel = Microsoft.Office.Interop.Excel;

    public partial class ThisAddIn  
    {
        public void ApplicationWorkbookBeforeSave(Excel.Workbook wb, bool saveAsUI, ref bool cancel)  
        {
            Excel.Worksheet activeWorksheet = (Excel.Worksheet)this.Application.ActiveSheet;
        }

        private void ThisAddIn_Startup(object sender, EventArgs e)  
        {
            this.Application.WorkbookBeforeSave += new Excel.AppEvents_WorkbookBeforeSaveEventHandler(this.ApplicationWorkbookBeforeSave); // used to connect Application_WorkbookBeforeSave event
            KeyboardHooking.SetHook();
        }

        private void ThisAddIn_Shutdown(object sender, EventArgs e) 
        {
            KeyboardHooking.ReleaseHook();
        }

        #region VSTO generated code

        private void InternalStartup()
        {
            this.Startup += new System.EventHandler(ThisAddIn_Startup);
            this.Shutdown += new System.EventHandler(ThisAddIn_Shutdown);
        }

        #endregion
    }
}
