public ConvertisForm1() 
    { 
     InitializeComponent(); 
     openFileDialog.Filter = "Files| *.chm;*.htm;*.html;*.rtf;*.xls;*.xlsx;*.xps;*.doc;*.docx";  
    dataGridView.AutoGenerateColumns = false; 
    dataGridView.RowHeadersVisible = false; 
    dataGridView.ColumnCount = 5; 

    dataGridView.RowCount = 20; 
    //delete button 
    var deleteDataGridViewButtonColumn = new DataGridViewButtonColumn 
    { 
     HeaderText = "", 
     Name = deleteDataGridViewButtonColumnName, 
     Text = "X", 
     Width =20 
    }; 
    dataGridView.Columns.Insert(DeleteColumnIndex, deleteDataGridViewButtonColumn); 

    dataGridView.Columns[FileNameAndPathColumnIndex].Width=250;

     Text = "...", 
     Width = 30

是这个dataGridView.ColumnCount = 5; ？ – active92

@ active92您不必提出这个问题。 :-) – LarsTech

你试过DataGridView1.AutoGenerateColumns = false;？

，或者你可以明确所有添加新列

他的autogeneratedcolumns已被设置为false，但他将他的列数设置为5.我认为这就是他获得5列的原因。 – active92

上帝保佑@TheQuestioner。删除ColumnCount = 5，清除列（在添加列之前）解决了问题。 –
