自动调整行和列

汽车配件

Aspose.Cells提供了一个类,工作簿,代表一个 Microsoft Excel 文件。这工作簿类包含一个工作表允许访问 Excel 文件中每个工作表的集合。

工作表由工作表班级。这工作表类提供了广泛的属性和方法来管理工作表。本文着眼于使用工作表自动调整行或列的类。

自动调整行 - 简单

自动调整行的宽度和高度的最直接的方法是调用工作表班级'[自动调整行](https://reference.aspose.com/cells/java/com.aspose.cells/worksheet#autoFitRow(int)) 方法。这[自动调整行](https://reference.aspose.com/cells/java/com.aspose.cells/worksheet#autoFitRow(int)方法将(要调整大小的行的)行索引作为参数。

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-Java
// The path to the documents directory.
String dataDir = Utils.getSharedDataDir(AutoFitRowsandColumns.class) + "rows_cloumns/";
// Instantiating a Workbook object
Workbook workbook = new Workbook(dataDir + "book1.xls");
// Accessing the first worksheet in the Excel file
Worksheet worksheet = workbook.getWorksheets().get(0);
// Auto-fitting the 2nd row of the worksheet
worksheet.autoFitRow(1);
// Auto-fitting the 1st column of the worksheet
worksheet.autoFitColumn(0);
// Saving the modified Excel file in default (that is Excel 2003) format
workbook.save(dataDir + "AutoFitRowsandColumns_out.xls");
// Print message
System.out.println("Row and Column auto fit successfully.");

Cells 范围内的 AutoFit 行

一行由许多列组成。 Aspose.Cells 允许开发人员通过调用[自动调整行](https://reference.aspose.com/cells/java/com.aspose.cells/worksheet#autoFitRow(int,%20int,%20int)) 方法。它采用以下参数:

  • 行索引,即将被自动调整的行的索引。
  • 第一列索引,该行第一列的索引。
  • 最后一列索引,该行最后一列的索引。

自动调整行 方法检查行中所有列的内容,然后自动调整行。

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-Java
// The path to the documents directory.
String dataDir = Utils.getSharedDataDir(AutoFitRowsinaRangeofCells.class) + "rows_cloumns/";
// Instantiating a Workbook object
Workbook workbook = new Workbook(dataDir + "book1.xls");
// Accessing the first worksheet in the Excel file
Worksheet worksheet = workbook.getWorksheets().get(0);
// Auto-fitting the row of the worksheet
worksheet.autoFitRow(1, 0, 5);
// Saving the modified Excel file in default (that is Excel 2003) format
workbook.save(dataDir + "AutoFitRowsinaRangeofCells_out.xls");
// Print message
System.out.println("Row auto fit successfully.");

自动调整列 - 简单

自动调整列的宽度和高度的最简单方法是调用工作表班级'[自动调整列](https://reference.aspose.com/cells/java/com.aspose.cells/worksheet#autoFitColumn(int)) 方法。这[自动调整列](https://reference.aspose.com/cells/java/com.aspose.cells/worksheet#autoFitColumn(int)方法将(即将调整大小的列的)列索引作为参数。

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-Java
// The path to the documents directory.
String dataDir = Utils.getSharedDataDir(AutoFitRowsandColumns.class) + "rows_cloumns/";
// Instantiating a Workbook object
Workbook workbook = new Workbook(dataDir + "book1.xls");
// Accessing the first worksheet in the Excel file
Worksheet worksheet = workbook.getWorksheets().get(0);
// Auto-fitting the 2nd row of the worksheet
worksheet.autoFitRow(1);
// Auto-fitting the 1st column of the worksheet
worksheet.autoFitColumn(0);
// Saving the modified Excel file in default (that is Excel 2003) format
workbook.save(dataDir + "AutoFitRowsandColumns_out.xls");
// Print message
System.out.println("Row and Column auto fit successfully.");

Cells 范围内的 AutoFit 列

一列由许多行组成。通过调用重载版本,可以根据列中单元格范围内的内容自动调整列[自动调整列](https://reference.aspose.com/cells/java/com.aspose.cells/worksheet#autoFitColumn(int,%20int,%20int)采用以下参数的方法:

  • 列索引代表内容需要自动适应的列的索引
  • 第一行索引代表该列第一行的索引
  • 最后一行索引代表该列最后一行的索引

这[自动调整列](https://reference.aspose.com/cells/java/com.aspose.cells/worksheet#autoFitColumn(int,%20int,%20int)方法检查列中所有行的内容,然后自动调整列。

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-Java
// The path to the documents directory.
String dataDir = Utils.getSharedDataDir(AutoFitColumnsinaRangeofCells.class) + "rows_cloumns/";
// Instantiating a Workbook object
Workbook workbook = new Workbook(dataDir + "book1.xls");
// Accessing the first worksheet in the Excel file
Worksheet worksheet = workbook.getWorksheets().get(0);
// Auto-fitting the Column of the worksheet
worksheet.autoFitColumn(4, 4, 6);
// Saving the modified Excel file in default (that is Excel 2003) format
workbook.save(dataDir + "AutoFitColumnsinaRangeofCells_out.xls");
// Print message
System.out.println("Columns auto fit successfully.");

合并的 AutoFit 行 Cells

使用 Aspose.Cells,即使对于已使用合并的单元格,也可以自动调整行AutoFitter选项 API. AutoFitter选项类提供AutoFitMergedCellsType可用于自动调整合并单元格行的属性。AutoFitMergedCellsType接受AutoFitMergedCellsType具有以下成员的可枚举。

// For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-Java
// The path to the documents directory.
String dataDir = Utils.getSharedDataDir(AutofitRowsforMergedCells.class) + "RowsAndColumns/";
// Instantiating a Workbook object
Workbook workbook = new Workbook();
// Accessing the first worksheet in the Excel file
Worksheet worksheet = workbook.getWorksheets().get(0);
// Create a range A1:B1
Range range = worksheet.getCells().createRange(0, 0, 1, 2);
// Merge the cells
range.merge();
// Insert value to the merged cell A1
worksheet.getCells().get(0, 0).setValue("A quick brown fox jumps over the lazy dog. A quick brown fox jumps over the lazy dog....end");
// Create a style object
Style style = worksheet.getCells().get(0, 0).getStyle();
// Set wrapping text on
style.setTextWrapped(true);
// Apply the style to the cell
worksheet.getCells().get(0, 0).setStyle(style);
// Create an object for AutoFitterOptions
AutoFitterOptions options = new AutoFitterOptions();
// Set auto-fit for merged cells
options.setAutoFitMergedCellsType(AutoFitMergedCellsType.EACH_LINE);
// Autofit rows in the sheet(including the merged cells)
worksheet.autoFitRows(options);
// Save the Excel file
workbook.save(dataDir + "AutofitRowsforMergedCells_out.xlsx");

您也可以使用的重载版本自动调整行 & [自动调整列](https://reference.aspose.com/cells/java/com.aspose.cells/worksheet#autoFitColumns() 方法接受一系列的行/列和一个实例AutoFitter选项使用所需的自动调整选定的行/列AutoFitter选项因此。

上述方法的签名如下:

  1. autoFitRows(int startRow,int endRow,AutoFitter选项选项)
  2. autoFitColumns(int firstColumn,int lastColumn,AutoFitter选项选项)
