要删除 DataColumn 来自 DataTable

 DataTable dt; 

你可以使用columName

 dt.Columns.Remove（  columnName）; 

或columnIndex

 dt .Columns.RemoveAt（columnIndex）; 

或类似这样

< blockquote> DataTable dt;

dt.Columns.Remove（columnName）;

dt.Columns.RemoveAt（columnIndex）;

只添加您想要的列，然后将 DataTable 中的列映射到 DataGridView 。

Eg

 buttonColumn.DataPropertyName =   ColumnNameInDataTable; 

现在只有你想要显示的列才可见。

解决方案

To remove DataColumn from DataTable

DataTable dt;

you can use columName

dt.Columns.Remove("columnName");

or columnIndex

dt.Columns.RemoveAt(columnIndex);

or like this

dt.Columns.Remove(dt.Columns[columnIndex]);

DataTable dt;
dt.Columns.Remove("columnName");
dt.Columns.RemoveAt(columnIndex);

You can add unbounded columns to your DataGridView How to: Add an Unbound Column to a Data-Bound Windows Forms DataGridView Control[^]

Add only the columns you want, then map the columns in the DataTable to the DataGridView.
E.g.

buttonColumn.DataPropertyName = "ColumnNameInDataTable";

Now only the columns you want to show will be visible.
