c# - GridView 列大小不更改 ASP.NET

Question

我正在尝试增加 gridview 中其中一列的大小，但是，无论我如何尝试增加大小，列宽都无法增加。 GridView 的数据正在我的 c# 代码中检索，该代码从我的数据库中获取数据。我检查了我的 gridview 类的 Css 代码，似乎没有什么影响列的宽度(或者至少我认为)。为什么我的列宽不会改变？

这是我目前的设置:ASP.NET:

 <div id="grid" style="overflow-x: auto; margin: auto; min-width: 100%; min-height: 100px; text-align: center;">
            <asp:Label runat="server" ID="empty" Font-Size="15px" Font-Bold="True" Visible="false"></asp:Label>
            <asp:GridView runat="server" ID="lessonsgrid" CssClass="gridview" AutoGenerateColumns="false">
                <Columns>
                    <asp:BoundField ItemStyle-Width="1%" HeaderText="Id" SortExpression="Id" DataField="Id" />
                    <asp:BoundField ItemStyle-Width="10%" HeaderText="Release" SortExpression="Release" DataField="Release" />
                    <asp:BoundField ItemStyle-Width="10%" HeaderText="Category" SortExpression="Category" DataField="Category" />
                    <asp:BoundField ItemStyle-Width="10%"  HeaderText="Subcategory" SortExpression="Subcategory" DataField="Subcategory" />
                    <asp:BoundField ItemStyle-Width="20%" ItemStyle-CssClass="descriptionCol" ItemStyle-HorizontalAlign="Left" HeaderText="Description" SortExpression="Description" DataField="Description" />
                    <asp:BoundField ItemStyle-Width="10%"  HeaderText="Identifying Team" SortExpression="Identifying Team" DataField="Identifying Team" />
                    <asp:BoundField ItemStyle-Width="5%"  HeaderText="Name" SortExpression="Name" DataField="Name" />
                    <asp:BoundField ItemStyle-Width="10%"  ItemStyle-HorizontalAlign="Left" HeaderText="Suggestions For Improvement" SortExpression="Suggestions For Improvement" DataField="Suggestions For Improvement" />
                    <asp:BoundField ItemStyle-Width="5%"  HeaderText="Team Assigned To" SortExpression="Team Assigned To" DataField="Team Assigned To" />
                    <asp:BoundField ItemStyle-Width="5%"  HeaderText="Implemented" SortExpression="Implemented" DataField="Implemented" />
                    <asp:BoundField ItemStyle-Width="5%"  HeaderText="Priority" SortExpression="Priority" DataField="Priority" />
                    <asp:BoundField ItemStyle-Width="5%"  HeaderText="Implement Complexity" SortExpression="Implement Complexity" DataField="Implement Complexity" />
                    <asp:BoundField ItemStyle-Width="10%"  HeaderText="Target Implement Date" SortExpression="Target Implement Date" DataField="Target Implement Date" />
                    <asp:BoundField ItemStyle-Width="10%"  ItemStyle-HorizontalAlign="Left" HeaderText="Comment" SortExpression="Comment" DataField="Comment" />
                </Columns>
            </asp:GridView>
        </div>

很遗憾，我还不能添加评论，但您在所有元素上都使用了百分比。需要有一个具有实际固定宽度的元素。这样，百分比就知道要占用该宽度的百分比。
