带有 FlowLayouts 的 TableLayoutPanel 中的 C# ScrollBar

Question

我有一行六列的 TableLayoutPanel。我正在为每一列添加一个 FlowLayoutPanel。在 FlowLayoutPanels 中，我正在添加动态控件。
我无法将控件直接添加到 TableLayoutPanel，因为添加和删除对于许多行而言太慢（从行中删除控件，然后将控件从下一行的行向上移动）。
但是当我向 FlowLayoutPanel 添加控件时，TableLayoutPanel 不显示 ScrollBar。

我有的是：
TableLayoutPanel: 1 行，6 列，DockStyle:Fill，AutoScroll:True
FlowLayoutPanel: DockStyle:Fill, FlowDirection:TopDown, WrapContents:False

ScrollBar 必须显示在 TableLayoutPanel 中。

示例代码（我认为它没有帮助，其余设置为可视模式）：

// create controls
CheckBox control1 = new CheckBox();
ComboBox control2 = new ComboBox();
ComboBox control3 = new ComboBox();
ComboBox control4 = new ComboBox();
ComboBox control5 = new ComboBox();
CheckBox control6 = new CheckBox();

control1.AutoSize   = false;
control1.CheckAlign = System.Drawing.ContentAlignment.MiddleCenter;

control3.DropDownStyle = ComboBoxStyle.DropDownList;
control3.Enabled       = false;

control4.DropDownStyle = ComboBoxStyle.DropDownList;
control4.Enabled       = false;

control5.DropDownStyle = ComboBoxStyle.DropDownList;
control5.Enabled       = false;

control6.AutoSize   = false;
control6.CheckAlign = System.Drawing.ContentAlignment.MiddleCenter;
control6.Enabled    = false;

// add to float layout panels
this.flayControl1.Controls.Add( control1 );
this.flayControl2.Controls.Add( control2 );
this.flayControl3.Controls.Add( control3 );
this.flayControl4.Controls.Add( control4 );
this.flayControl5.Controls.Add( control5 );
this.flayControl6.Controls.Add( control6 );

还有图片，如你所见，左侧没有滚动条，但控件隐藏在最后（TableLayoutPanel 是带边框的控件）：

感谢Reza Aghaei，我是这样解决的：

我创建了 FlowLayoutPanel，然后，我为 FlowLayoutPanel 中的每一行创建了 TableLayoutPanel。

int pad1, pad2, height = 28;

FlowLayoutPanel panel = new FlowLayoutPanel();
panel.AutoScroll = true;
panel.FlowDirection = FlowDirection.TopDown;
panel.WrapContents = false;

for( int x = 0; x < 10; ++x )
{
    TableLayoutPanel table = new TableLayoutPanel();
    table.Width = panel.Width;

    // controls
    CheckBox control1 = new CheckBox();
    ComboBox control2 = new ComboBox();
    ComboBox control3 = new ComboBox();
    TextBox  control4 = new TextBox();
    TextBox  control5 = new TextBox();
    CheckBox control6 = new CheckBox();

    // columns and rows number
    table.ColumnCount = 6;
    table.RowCount    = 1;

    // row height
    table.RowStyles.Add( new RowStyle(SizeType.Absolute, height) );

    // widths of columns
    table.ColumnStyles.Add( new ColumnStyle(SizeType.Percent, 5.0f ) );
    table.ColumnStyles.Add( new ColumnStyle(SizeType.Percent, 24.0f) );
    table.ColumnStyles.Add( new ColumnStyle(SizeType.Percent, 20.0f) );
    table.ColumnStyles.Add( new ColumnStyle(SizeType.Percent, 22.0f) );
    table.ColumnStyles.Add( new ColumnStyle(SizeType.Percent, 24.0f) );
    table.ColumnStyles.Add( new ColumnStyle(SizeType.Percent, 5.0f ) );

    // fill
    control1.Dock = control2.Dock = control3.Dock = control4.Dock =
    control5.Dock = control6.Dock = DockStyle.Fill;

    // margin
    pad1 = (height - control2.Height) / 2;
    pad2 = height - control2.Height - pad1;

    control2.Margin = control3.Margin = new Padding( 2, pad1, 2, pad2 );

    // textboxes margin
    pad1 = (height - control4.Height) / 2;
    pad2 = height - control4.Height - pad1;

    control4.Margin = control5.Margin = new Padding( 2, pad1, 2, pad2 );

    // add elements to TableLayoutPanel
    table.Controls.Add( control1, 0, 0 );
    table.Controls.Add( control2, 1, 0 );
    table.Controls.Add( control3, 2, 0 );
    table.Controls.Add( control4, 3, 0 );
    table.Controls.Add( control5, 4, 0 );
    table.Controls.Add( control6, 5, 0 );

    // add table to FlowLayoutPanel
    panel.Controls.Add( table );
}

此代码在 FlowLayoutPanel 中创建 10 行。
