winform下控制每个列的宽度[原创]

在做winform的程序时，经常遇到不能调节DataGrid列宽的情况，查了不少资料后，写了个函数。希望大家能多多提出改进的意见。谢谢。

public static DataGridTableStyle SetGrid(DataTable Table,string[] WidthArr,string[] HeadText,string[] MapName)
        {
            if(Table.Columns.Count == WidthArr.Length || Table.Columns.Count == HeadText.Length || Table.Columns.Count == MapName.Length)
            {
                DataGridTableStyle GridStyle = new DataGridTableStyle();
                GridStyle.MappingName = Table.TableName;  
                for(int i=0;i<Table.Columns.Count;i++)
                {
                    DataGridTextBoxColumn CStyle = new DataGridTextBoxColumn();
                    CStyle.HeaderText = HeadText[i];
                    CStyle.MappingName = MapName[i];
                    CStyle.Width = Convert.ToInt32(WidthArr[i]);
                    if(Convert.ToInt32(WidthArr[i]) <= 30)
                    {
                        CStyle.Alignment = System.Windows.Forms.HorizontalAlignment.Center;
                    }
                    else
                    {
                        CStyle.Alignment = System.Windows.Forms.HorizontalAlignment.Center;
                    }                    
                    GridStyle.GridColumnStyles.Add(CStyle);
                }                
                return GridStyle;
            }
            else
            {
                return null;
            }
        }

    用法：
    this.libData.DataSource = Table;   
   string[] WidthArr = {"20","80","100","100","0"};
   string[] HeadArr  = {"","PK","ZD","KD","ID"};
   string[] MapArr   = {"ID","PK","ZD","KD","OID"};
   DataGridTableStyle st1 = GridStyle.SetGrid(Table,WidthArr,HeadArr,MapArr);
