或者這樣的報表格式
首先來分析第一種報表,這個其實還是比較固定的二維表,我們隻要綁定相關的資訊即可,設計模闆如下所示:
實際生成的報表如下所示:
實作的代碼其實不複雜,如下所示:
private DataTable GetTable(string sql)
{
Database db = DatabaseFactory.CreateDatabase();
DbCommand command = db.GetSqlStringCommand(sql);
return db.ExecuteDataSet(command).Tables[0];
}
private void btnAllMonthReport_Click(object sender, EventArgs e)
string sql = @"Select [LastCount] as LC, [LastMoney] as LM, [CurrentInCount] as CIC, [CurrentInMoney] as CIM,
[CurrentOutCount] as COC, [CurrentOutMoney] as COM, [CurrentCount] as CC, [CurrentMoney] as CM,
YearMonth,ItemName
from TB_ReportMonthCheckOut ";
DataTable dtBigType = GetTable(sql + " where ReportType =3");
dtBigType.TableName = "BigType";
if (dtBigType.Rows.Count == 0)
return;
DataTable dtItemType = GetTable(sql + " where ReportType =3");
dtItemType.TableName = "ItemType";
WorkbookDesigner designer = new WorkbookDesigner();
string path = System.IO.Path.Combine(Application.StartupPath, "Report2-1.xls");
designer.Open(path);
designer.SetDataSource(dtBigType);
designer.SetDataSource(dtItemType);
designer.SetDataSource("YearMonth", dtBigType.Rows[0]["YearMonth"].ToString());
designer.Process();
//Save the excel file
string fileToSave = FileDialogHelper.SaveExcel();
if (File.Exists(fileToSave))
{
File.Delete(fileToSave);
}
designer.Save(fileToSave, FileFormatType.Excel2003);
Process.Start(fileToSave);
通過綁定兩個不同的DataTable對象,然後引用他的屬性即可,行會自動增加以适應實際的資料,并且對象變量&=$YearMonth也正常顯示了,注意一點就是,所有使用變量的地方,都必須在一個獨立的Excel單元格中,否則不能解析出來。另外上圖的紅色圓圈裡面表示,彙總的函數,會自動根據行列的增加,自動調整引用,這真是我們需要的。
出庫單的實作也差不多,實作代碼如下所示:
string TakeOutBill = Path.Combine(Application.StartupPath, "TakeOutBill.xls");
designer.Open(TakeOutBill);
designer.SetDataSource("TakeOutDate", DateTime.Now.ToString("yyyy-MM-dd"));
designer.SetDataSource("WareHouse", this.txtWareHouse.Text);
designer.SetDataSource("Manager", this.txtCreator.Text);
designer.SetDataSource("CostCenter", this.txtCostCenter.Text);
designer.SetDataSource("Dept", this.txtDept.Text);
string columns = "Start|int,ItemNo,ItemName,Specification,Unit,Price|decimal,Count|int";
DataTable dt = DataTableHelper.CreateTable(columns);
dt.TableName = "Detail";
DataRow row = null;
for (int i = 0; i < this.lvwDetail.Items.Count; i++)
PurchaseDetailInfo info = this.lvwDetail.Items[i].Tag as PurchaseDetailInfo;
if (info != null)
{
row = dt.NewRow();
row["Start"] = (i + 1);
row["ItemNo"] = info.ItemNo;
row["ItemName"] = info.ItemName;
row["Specification"] = info.Specification;
row["Unit"] = info.Unit;
row["Price"] = info.Price;
row["Count"] = Math.Abs(info.Quantity);
dt.Rows.Add(row);
}
designer.SetDataSource(dt);
Process.Start(fileToSave);
以上報表,其實實作思路基本都差不多,相對來時,還是比較容易的,接下來設計一個比較困難的報表,需要結合Aspose.Cell一些對象來動态建立行列,并設定單元格的變量,然後填入相應的對象構造報表,另外還需要注意單元格格式的變化,如下所示的這種報表
這個報表初看沒有太多特别的地方,難點就是他的第一行列也是變化的,是以不能通過普通的方式建構二維表,然後綁定資料源的方式,要先加載模闆檔案,然後操作Excel對象,把第一行的各列頭部補齊,然後給下一行各單元格填入對象公式,如&=BigType.DeptName 和&=BigType.TotalMoney等内容,實作的代碼如下所示:
string sql = @"Select [YearMonth], [DeptName], [ItemType], [TotalMoney]
from TB_ReportDeptCost ";
DataTable dt = GetTable(sql);
if (dt.Rows.Count == 0)
List<string> itemTypeList = new List<string>();
List<string> partList = new List<string>();
foreach (DataRow row in dt.Rows)
string itemType = row["ItemType"].ToString();
if (!itemTypeList.Contains(itemType))
itemTypeList.Add(itemType);
string part = row["DeptName"].ToString();
if (!partList.Contains(part))
partList.Add(part);
string columnString = "DeptName";
for (int i = 0; i < itemTypeList.Count; i++)
columnString += string.Format(",TotalMoney{0}|decimal", i);
DataTable dtBigType = DataTableHelper.CreateTable(columnString);
foreach (string part in partList)
DataRow row = dtBigType.NewRow();
row["DeptName"] = part;
for (int i = 0; i < itemTypeList.Count; i++)
string itemType = itemTypeList[i];
DataRow[] rowSelect = dt.Select(string.Format("DeptName='{0}' AND ItemType='{1}'", part, itemType));
if (rowSelect.Length > 0)
{
row["TotalMoney" + i.ToString()] = rowSelect[0]["TotalMoney"];
}
dtBigType.Rows.Add(row);
string path = System.IO.Path.Combine(Application.StartupPath, "Report1.xls");
Aspose.Cells.Worksheet w = designer.Workbook.Worksheets[0];
//先設定标題項目:如大修件,日常備件等
int rowIndex = 2;//第三行為标題
Aspose.Cells.Style style = w.Cells[rowIndex + 1, 1].Style;//繼承數字欄目的樣式
style.Number = 4;//對應格式是#,##0.00
Aspose.Cells.Style boldStyle = w.Cells[rowIndex, 0].Style;//繼承開始欄目的樣式
w.Cells[rowIndex, i + 1].PutValue(itemTypeList[i]);
w.Cells[rowIndex, i + 1].Style = boldStyle;
w.Cells[rowIndex + 1, i + 1].PutValue("&=BigType.TotalMoney" + i.ToString());
w.Cells[rowIndex + 1, i + 1].Style = style;
//添加合計行
w.Cells[rowIndex, itemTypeList.Count + 1].PutValue("合計");
w.Cells[rowIndex, itemTypeList.Count + 1].Style = boldStyle;
w.Cells[rowIndex + 1, itemTypeList.Count + 1].PutValue(string.Format("&=&=SUM(B{{r}}:{0}{{r}})", GetChar(itemTypeList.Count + 1)));
w.Cells[rowIndex + 1, itemTypeList.Count + 1].Style = style;
designer.SetDataSource("YearMonth", dt.Rows[0]["YearMonth"].ToString());
Process.Start(fileToSave);
