请问如何C#实例化一个已经打开的EXCEL工作薄。（假设文件名是1.xls）？

Workbook wb = new Workbook()

Worksheet ws = wb.Worksheets[0]

Cells cell = ws.Cells

//定义并获取导出的数据源

string[,] _ReportDt = new string[table.Rows.Count, table.Columns.Count]

for (int i = 0i <槐伍 table.Rows.Counti++)

{

for (int j = 0j <table.Columns.Countj++)

{

_ReportDt[i, j] = Convert.ToString(table.Rows[i][j])

}

}

int columnstart = 0

//设置行高

for (int k = 0k <= columnstartk++) { cell.SetRowHeight(k, 24)}

//设置字体样式铅漏或

Style style0 = wb.Styles[wb.Styles.Add()]

style0.HorizontalAlignment = TextAlignmentType.Center//文字居中

style0.Font.Name = "宋体"

style0.Font.IsBold = true//设置粗体

style0.Font.Size = 10//设置字体大小搜御

Style style1 = wb.Styles[wb.Styles.Add()]

style1.HorizontalAlignment = TextAlignmentType.Center//文字居中

style1.Font.Name = "宋体"

style1.Font.Size = 10//设置字体大小

style1.BackgroundColor = System.Drawing.Color.BlueViolet

style1.ForegroundColor = System.Drawing.Color.White

style1.Borders[BorderType.TopBorder].LineStyle = CellBorderType.Thin

style1.Borders[BorderType.TopBorder].Color = Color.Black

style1.Borders[BorderType.BottomBorder].LineStyle = CellBorderType.Thin

style1.Borders[BorderType.BottomBorder].Color = Color.Black

style1.Borders[BorderType.LeftBorder].LineStyle = CellBorderType.Thin

style1.Borders[BorderType.LeftBorder].Color = Color.Black

style1.Borders[BorderType.RightBorder].LineStyle = CellBorderType.Thin

style1.Borders[BorderType.RightBorder].Color = Color.Black

Style style2 = wb.Styles[wb.Styles.Add()]

style2.HorizontalAlignment = TextAlignmentType.Left

style2.Font.Size = 9

style2.Borders[BorderType.TopBorder].LineStyle = CellBorderType.Thin

style2.Borders[BorderType.TopBorder].Color = Color.Black

style2.Borders[BorderType.BottomBorder].LineStyle = CellBorderType.Thin

style2.Borders[BorderType.BottomBorder].Color = Color.Black

style2.Borders[BorderType.LeftBorder].LineStyle = CellBorderType.Thin

style2.Borders[BorderType.LeftBorder].Color = Color.Black

style2.Borders[BorderType.RightBorder].LineStyle = CellBorderType.Thin

style2.Borders[BorderType.RightBorder].Color = Color.Black

//给单元格关联样式

for (int k = 0k <= columnstartk++)

{

if (k == 0)

{

cell["A" + (k + 1).ToString()].SetStyle(style0)

}

else

{

cell["A" + (k + 1).ToString()].SetStyle(style1)

}

}

//设置Execl列名

for (int i = 0i <table.Columns.Counti++)

{

cell[columnstart, i].PutValue(Convert.ToString(table.Columns[i].ColumnName))

cell[columnstart, i].SetStyle(style1)

}

//设置单元格内容

int posStart = columnstart + 1

for (int i = 0i <table.Rows.Counti++)

{

for (int j = 0j <table.Columns.Countj++)

{

if (j == 9)

{

int sy = _ReportDt[i, j] == "0" ? 0 : Convert.ToInt32(_ReportDt[i, j])

cell[i + posStart, j].PutValue(sy)

cell[i + posStart, j].SetStyle(style2)

}

else

{

string sy = _ReportDt[i, j] == "0" ? "" : Convert.ToString(_ReportDt[i, j])

cell[i + posStart, j].PutValue(sy)

cell[i + posStart, j].SetStyle(style2)

}

}

}

//设置列宽

if (columnwidth != null)

{

for (int i = 0i <table.Columns.Counti++)

{

cell.SetColumnWidth(i, Convert.ToDouble(columnwidth[i].ToString("0")))

}

}

//保存excel表格

wb.Save(path)

System.Diagnostics.Process.Start(path)

Vue.js是一个前端JavaScript框架，它需要在页宽搜面中引入其主文件，通神坦常是 vue.min.js 或 vue.js。在引入之后，才能使用 Vue.js 的所有功能，包括实例化一个 Vue 对象。因此，在实例化之游巧桐前必须引入 Vue 的 core 文件。

引用路径不亏启对，铅空野需要使用相对的绝对路径，如

include __DIR__ . '/../../Component/PHPExcel.php'；

其中 __DIR__ 是ExcelController这个文件所在槐喊的目录
