如何用c#设置gridview数据的填充

我已经用c#填充了gridview，但是girdview中的数据非常接近单元格边界。我如何用c#去掉单元格内容的填充?

string query = "SELECT * FROM `fabrica`";
//'bd' and 'ExecuteRead' is my database classe
DataTable table = bd.ExecuteRead(query);
table.Columns["id"].ColumnName = "ID";
table.Columns["nome"].ColumnName = "Nome";
table.Columns["cidade"].ColumnName = "Cidade";
table.Columns["estado"].ColumnName = "Estado";
table.Columns["telefone1"].ColumnName = "Telefone 1";
table.Columns["telefone2"].ColumnName = "Telefone 2";
table.Columns["telefone3"].ColumnName = "Telefone 3";
table.Columns["email1"].ColumnName = "Email 1";
table.Columns["email2"].ColumnName = "Email 2";
table.Columns["email3"].ColumnName = "Email 3";
Tabela.DataSource = table;
Tabela.ControlStyle.Width = 885;
Tabela.DataBind();

Tabela.CellPadding = 10;
