对齐设置

配置对齐设置

Microsoft Excel中的对齐设置

任何使用Microsoft Excel格式化单元格的人都会熟悉Microsoft Excel中的对齐设置。

从上面的图中可以看出，有不同种类的对齐选项：

• 文本对齐(水平和垂直)
• 缩进
• 方向
• 文本控制
• 文本方向

所有这些对齐设置都得到了Aspose.Cells for Python via .NET的全面支持，详细内容如下。

Aspose.Cells for Python via .NET中对齐设置

Aspose.Cells for Python via .NET提供一个类 Workbook，代表一个Excel文件。Workbook 类包含一个 worksheets 集合，可访问Excel文件中的每个工作表。工作表由 Worksheet 类表示。Worksheet 类提供一个 cells 集合。cells 集合中的每个项目代表一个 Cell 类的对象。

Aspose.Cells for Python via .NET为 Cell 类提供 get_style 和 set_style 方法，用于获取和设置单元格的格式。Style 类提供有用的属性，用于配置对齐设置。

使用TextAlignmentType枚举选择任何文本对齐类型。TextAlignmentType枚举中预定义的文本对齐类型包括：

文本对齐类型	描述
GENERAL	表示常规文本对齐方式
BOTTOM	表示底部文本对齐
CENTER	表示居中对齐
CENTER_ACROSS	表示跨列居中对齐
DISTRIBUTED	表示分散对齐
FILL	表示填充对齐
JUSTIFY	表示两端对齐
LEFT	表示左对齐
RIGHT	表示右对齐
TOP	表示顶部对齐
JUSTIFIED_LOW	对阿拉伯语文本进行调整卡希达长度的两端对齐
THAI_DISTRIBUTED	特别分布泰语文本，因为每个字符被视为一个词

您还可以使用Style.is_justify_distributed属性应用两端对齐分布设置。

水平对齐

使用Style对象的horizontal_alignment属性使文本水平对齐。

from aspose.cells import SaveFormat, TextAlignmentType, Workbook
from os import os, path

#  For complete examples and data files, please go to https:# github.com/aspose-cells/Aspose.Cells-for-.NET
#  The path to the documents directory.
dataDir = RunExamples.GetDataDir(".")
#  Create directory if it is not already present.
IsExists = path.isdir(dataDir)
if notIsExists:
    os.makedirs(dataDir)
#  Instantiating a Workbook object
workbook = Workbook()
#  Obtaining the reference of the worksheet
worksheet = workbook.worksheets[0]
#  Accessing the "A1" cell from the worksheet
cell = worksheet.cells.get("A1")
#  Adding some value to the "A1" cell
cell.put_value("Visit Aspose!")
#  Setting the horizontal alignment of the text in the "A1" cell
style = cell.get_style()
style.horizontal_alignment = TextAlignmentType.CENTER
cell.set_style(style)
#  Saving the Excel file
workbook.save(dataDir + "book1.out.xls", SaveFormat.EXCEL_97_TO_2003)

垂直对齐

与水平对齐类似，使用 Style 对象的 vertical_alignment 属性来垂直对齐文本。

from aspose.cells import SaveFormat, TextAlignmentType, Workbook
from os import os, path

#  For complete examples and data files, please go to https:# github.com/aspose-cells/Aspose.Cells-for-.NET
#  The path to the documents directory.
dataDir = RunExamples.GetDataDir(".")
#  Create directory if it is not already present.
IsExists = path.isdir(dataDir)
if notIsExists:
    os.makedirs(dataDir)
#  Instantiating a Workbook object
workbook = Workbook()
#  Clearing all the worksheets
workbook.worksheets.clear()
#  Adding a new worksheet to the Excel object
i = workbook.worksheets.add()
#  Obtaining the reference of the newly added worksheet by passing its sheet index
worksheet = workbook.worksheets[i]
#  Accessing the "A1" cell from the worksheet
cell = worksheet.cells.get("A1")
#  Adding some value to the "A1" cell
cell.put_value("Visit Aspose!")
#  Setting the horizontal alignment of the text in the "A1" cell
style = cell.get_style()
#  Setting the vertical alignment of the text in a cell
style.vertical_alignment = TextAlignmentType.CENTER
cell.set_style(style)
#  Saving the Excel file
workbook.save(dataDir + "book1.out.xls", SaveFormat.EXCEL_97_TO_2003)

缩进

可以使用 Style 对象的 indent_level 属性来设置单元格中文本的缩进级别。

from aspose.cells import SaveFormat, Workbook
from os import os, path

#  For complete examples and data files, please go to https:# github.com/aspose-cells/Aspose.Cells-for-.NET
#  The path to the documents directory.
dataDir = RunExamples.GetDataDir(".")
#  Create directory if it is not already present.
IsExists = path.isdir(dataDir)
if notIsExists:
    os.makedirs(dataDir)
#  Instantiating a Workbook object
workbook = Workbook()
#  Obtaining the reference of the worksheet
worksheet = workbook.worksheets[0]
#  Accessing the "A1" cell from the worksheet
cell = worksheet.cells.get("A1")
#  Adding some value to the "A1" cell
cell.put_value("Visit Aspose!")
#  Setting the horizontal alignment of the text in the "A1" cell
style = cell.get_style()
#  Setting the indentation level of the text (inside the cell) to 2
style.indent_level = 2
cell.set_style(style)
#  Saving the Excel file
workbook.save(dataDir + "book1.out.xls", SaveFormat.EXCEL_97_TO_2003)

方向

使用 Style 对象的 rotation_angle 属性来设置单元格中文本的方向（旋转）。

from aspose.cells import SaveFormat, Workbook
from os import os, path

#  For complete examples and data files, please go to https:# github.com/aspose-cells/Aspose.Cells-for-.NET
#  The path to the documents directory.
dataDir = RunExamples.GetDataDir(".")
#  Create directory if it is not already present.
IsExists = path.isdir(dataDir)
if notIsExists:
    os.makedirs(dataDir)
#  Instantiating a Workbook object
workbook = Workbook()
#  Obtaining the reference of the worksheet
worksheet = workbook.worksheets[0]
#  Accessing the "A1" cell from the worksheet
cell = worksheet.cells.get("A1")
#  Adding some value to the "A1" cell
cell.put_value("Visit Aspose!")
#  Setting the horizontal alignment of the text in the "A1" cell
style = cell.get_style()
#  Setting the rotation of the text (inside the cell) to 25
style.rotation_angle = 25
cell.set_style(style)
#  Saving the Excel file
workbook.save(dataDir + "book1.out.xls", SaveFormat.EXCEL_97_TO_2003)

文本控制

以下部分讨论了如何通过设置文本换行、缩小以适应和其他格式设置选项来控制文本。

自动换行文本

在单元格中设置文本换行可使其更易读：单元格的高度会根据文本内容自动调整，而不会被截断或溢出到相邻单元格。可以使用 Style 对象的 is_text_wrapped 属性来设置文本换行开或关闭。

from aspose.cells import Workbook

#  For complete examples and data files, please go to https:# github.com/aspose-cells/Aspose.Cells-for-.NET
#  The path to the documents directory.
dataDir = RunExamples.GetDataDir(".")
#  Create Workbook Object
wb = Workbook()
#  Open first Worksheet in the workbook
ws = wb.worksheets[0]
#  Get Worksheet Cells Collection
cell = ws.cells
#  Increase the width of First Column Width
cell.set_column_width(0, 35)
#  Increase the height of first row
cell.set_row_height(0, 36)
#  Add Text to the Firts Cell
cell.get(0, 0).put_value("I am using the latest version of Aspose.Cells to test this functionality")
#  Make Cell's Text wrap
style = cell.get(0, 0).get_style()
style.is_text_wrapped = True
cell.get(0, 0).set_style(style)
#  Save Excel File
wb.save(dataDir + "WrappingText.out.xlsx")

缩小以适应

在单元格中设置文本字段换行的选项是缩小文本大小以适应单元格尺寸，可以通过将 Style 对象的 is_text_wrapped 属性设置为 true 来实现。

from aspose.cells import SaveFormat, Workbook
from os import os, path

#  For complete examples and data files, please go to https:# github.com/aspose-cells/Aspose.Cells-for-.NET
#  The path to the documents directory.
dataDir = RunExamples.GetDataDir(".")
#  Create directory if it is not already present.
IsExists = path.isdir(dataDir)
if notIsExists:
    os.makedirs(dataDir)
#  Instantiating a Workbook object
workbook = Workbook()
#  Obtaining the reference of the worksheet
worksheet = workbook.worksheets[0]
#  Accessing the "A1" cell from the worksheet
cell = worksheet.cells.get("A1")
#  Adding some value to the "A1" cell
cell.put_value("Visit Aspose!")
#  Setting the horizontal alignment of the text in the "A1" cell
style = cell.get_style()
#  Shrinking the text to fit according to the dimensions of the cell
style.shrink_to_fit = True
cell.set_style(style)
#  Saving the Excel file
workbook.save(dataDir + "book1.out.xls", SaveFormat.EXCEL_97_TO_2003)

合并单元格

像Microsoft Excel一样，Aspose.Cells for Python via .NET支持将多个单元格合并为一个。Aspose.Cells for Python via .NET提供两种方法实现此操作。一种方法是调用 cells 集合的 merge 方法。merge 方法需要以下参数以合并单元格：

• 第一行：开始合并的第一行。
• 第一列：开始合并的第一列。
• 行数：要合并的行数。
• 列数：要合并的列数。

from aspose.cells import BackgroundType, Workbook
from aspose.pydrawing import Color
from os import os, path

#  For complete examples and data files, please go to https:# github.com/aspose-cells/Aspose.Cells-for-.NET
#  The path to the documents directory.
dataDir = RunExamples.GetDataDir(".")
#  Create directory if it is not already present.
IsExists = path.isdir(dataDir)
if notIsExists:
    os.makedirs(dataDir)
#  Create a Workbook.
wbk = Workbook()
#  Create a Worksheet and get the first sheet.
worksheet = wbk.worksheets[0]
#  Create a Cells object ot fetch all the cells.
cells = worksheet.cells
#  Merge some Cells (C6:E7) into a single C6 Cell.
cells.merge(5, 2, 2, 3)
#  Input data into C6 Cell.
worksheet.cells.get(5, 2).put_value("This is my value")
#  Create a Style object to fetch the Style of C6 Cell.
style = worksheet.cells.get(5, 2).get_style()
#  Create a Font object
font = style.font
#  Set the name.
font.name = "Times New Roman"
#  Set the font size.
font.size = 18
#  Set the font color
font.color = Color.blue
#  Bold the text
font.is_bold = True
#  Make it italic
font.is_italic = True
#  Set the backgrond color of C6 Cell to Red
style.foreground_color = Color.red
style.pattern = BackgroundType.SOLID
#  Apply the Style to C6 Cell.
cells.get(5, 2).set_style(style)
#  Save the Workbook.
wbk.save(dataDir + "mergingcells.out.xls")

另一种方法是首先调用 cells 集合的 create_range 方法来创建要合并的单元格范围。create_range 方法接受与上述 merge 方法相同的参数集，并返回一个 Range 对象。Range 对象还提供一个 merge 方法，该方法合并 Range 对象中指定的范围。

文本方向

可以设置单元格中文本的阅读顺序。阅读顺序是以字符、单词等显示的视觉顺序。例如，英语是从左到右的语言，而阿拉伯语是从右到左的语言。

读取顺序通过 Style 对象的 text_direction 属性设置。Aspose.Cells for Python via .NET提供了在 TextDirectionType 枚举中预定义的文本方向类型。

文本方向类型	描述
CONTEXT	与首个输入字符的语言一致的阅读顺序
LEFT_TO_RIGHT	从左到右的阅读顺序
RIGHT_TO_LEFT	从右到左的阅读顺序

from aspose.cells import TextDirectionType, Workbook

#  Instantiating a Workbook object
workbook = Workbook()
#  Obtaining the reference of first worksheet
worksheet = workbook.worksheets[0]
#  Accessing the "A1" cell from the worksheet
cell = worksheet.cells.get("A1")
#  Adding some value to the "A1" cell
cell.put_value("I am using the latest version of Aspose.Cells to test this functionality.")
#  Gets style in the "A1" cell
style = cell.get_style()
#  Shrinking the text to fit according to the dimensions of the cell
style.text_direction = TextDirectionType.LEFT_TO_RIGHT
cell.set_style(style)
#  Saving the Excel file
workbook.save("book1.xlsx")
