这篇简短的文字对单元格的操作总结的比较全面,特此转载过来。

Excel Interior.ColorIndex色彩列表

对用的Interior.ColorIndex色彩列表。

在C# 对Excel编程中的使用:

 for (int i = 5; i < countRow + 1; i++)
                string strKB = null;
                Microsoft.Office.Interop.Excel.Range kbrng = (Microsoft.Office.Interop.Excel.Range)sheSource.Cells[i, 1];
                if (kbrng.Value2 != null)
                    strKB = kbrng.Value2.ToString();
                if (strTotal.Contains(strKB))
                    kbrng.Interior.ColorIndex = 3;

二、常见的Excel单元格格式设置内容

2.1 数字(Range.NumberFormatlocal 属性)

Range.NumberFormatlocal = "G/通用格式"

Range.NumberFormatlocal = "0.000_" --保留小 数位数为3  (此处“_”表示:留下一个与下一个字符同等宽度的空格)

Range.NumberFormatlocal = "0" --不要小数

Range.NumberFormatlo cal = "#,##0.000" --保留小数位数为3,并使用千位分隔符
货币:

Range.NumberFormatlocal = "$#,##0.000"
百分比:

Range.NumberFormatlocal = "0.000%"
分数:

Range.NumberFormatlocal = "# ?/?"
科学计数:

Range.NumberFormatlocal = "0.00E+00"

Range.NumberFormatlocal = "@"

Range.NumberFormatlocal = "000000"---邮政编码
Range.NumberFormatlocal = "[DBNum1]G/通用格式"---中文小写数字
Range.NumberFormatlocal = "[DBNum2]G/通用格式"---中文大写数字
Range.NumberFormatlocal = "[DBNum2][$RMB]G/通用格式"---人民币大写

2.2 对齐

水平对齐:Range.HorizontalAlignment = etHAlignCenter  ---居中
垂 直对齐:Range.VerticalAlignment = etVAlignCenter---居中
是否自动换行:Range.WrapText = True
是否缩小字体填充:Range.ShrinkToFit = True
是否合并单元格:Range.MergeCells = False
文字竖排:Range.Orientation = etVertical
文字倾斜度数:Range.Orientation = 45 -----倾斜45度
字体(Font对象)
字体名称:Font.Name = "华文行楷"
字形: Font.FontStyle = "常规"
字号:Font.Size = "10"
下划线:Font.Strikethrough = True; Font.Underline = etUnderlineStyleDouble ---双下划线
上标:Font.Superscript = True
下 标:Font.SubScript = True
删除线:Font.OutlineFont = True

2.3 边框(Borders对象)

Borders.Item(etEdgeTop):上边框
Borders.Item(etEdgeLeft):左边框
Borders.Item (etEdgeRight):右边框
Borders.Item(etEdgeBottom):下边框
Borders.Item(etDiagonalDown) :左上--右下边框
Borders.Item(etDiagonalUp):左下--右上边框
Border.LineStyle = etContinuous 线条样式

PhpSpreadsheet生成Excel时实现单元格自动换行
PhpSpreadsheet是PHPExcel的替代版本,PHPExcel的作者已经停止了更新,今天尝试了使用PhpSpreadsheet生成Excel的时候支持单元格内的自动换行,发现用法其实差不多。
