@squirrelfeng You need to append the ColumnListBlock with supported ColumBlock based on how many columns you need. Attach the Children blocks inside the column need.

Simple Example.

This add two columns with a heading block as child on a page.

var leftColumn = new ColumnBlockRequest()
{
	Column = new ColumnBlockRequest.Info()
	{
		Children = new[]
		{
			new HeadingOneBlockRequest()
			{
				Heading_1 = new HeadingOneBlockRequest.Info()
				{
					RichText = new List<RichTextBase>()
					{
						new RichTextTextInput()
						{
							Text = new Text() { Content = "Left" }
						}
					}
				}
			}
		}
	}
};

var rightColumn = new ColumnBlockRequest()
{
	Column = new ColumnBlockRequest.Info()
	{
		Children = new[]
		{
			new HeadingOneBlockRequest()
			{
				Heading_1 = new HeadingOneBlockRequest.Info()
				{
					RichText = new List<RichTextBase>()
					{
						new RichTextTextInput()
						{
							Text = new Text() { Content = "Right" }
						}
					}
				}
			}
		}
	}
};

var request = new BlockAppendChildrenRequest()
{
	BlockId = _page.Id,
	Children = new List<IBlockObjectRequest>()
	{
		new ColumnListBlockRequest()
		{
			ColumnList = new ColumnListBlockRequest.Info()
			{
				Children = new List<ColumnBlockRequest>()
				{
					leftColumn,
					rightColumn
				}
			}
		}
	}
};

await Client.Blocks.AppendChildrenAsync(request);
