使用C++更改单元格对齐方式并保持现有格式

可能的使用场景

有时,您想要更改多个单元格的对齐方式,但又希望保持现有的格式。Aspose.Cells允许使用GetAlignments()属性实现这一点。如果将其设置为true,对齐变更将生效,否则不变。请注意,StyleFlag对象作为参数传递给ApplyStyle(const Style& style, const StyleFlag& flag)方法,而该方法实际应用格式到一系列单元格。

更改单元格对齐方式并保留现有格式

以下示例代码加载了示例Excel文件(67338585.xlsx),创建范围并将其在水平和垂直方向上居中对齐,并保持现有格式不变。以下屏幕截图比较了示例Excel文件和输出Excel文件(67338586.xlsx),并显示了所有单元格的现有格式相同,只是单元格现在在水平和垂直方向上都居中对齐。

示例代码

#include <iostream>
#include "Aspose.Cells.h"
using namespace Aspose::Cells;

int main()
{
    Aspose::Cells::Startup();

    // For complete examples and data files, please go to https://github.com/aspose-cells/Aspose.Cells-for-C

    // Load sample Excel file containing cells with formatting.
    U16String sourceDir(u"..\\Data\\01_SourceDirectory\\");
    U16String outputDir(u"..\\Data\\02_OutputDirectory\\");
    Workbook wb(sourceDir + u"sampleChangeCellsAlignmentAndKeepExistingFormatting.xlsx");

    // Access first worksheet.
    Worksheet ws = wb.GetWorksheets().Get(0);

    // Create cells range.
    Range rng = ws.GetCells().CreateRange(u"B2:D7");

    // Create style object.
    Style st = wb.CreateStyle();

    // Set the horizontal and vertical alignment to center.
    st.SetHorizontalAlignment(TextAlignmentType::Center);
    st.SetVerticalAlignment(TextAlignmentType::Center);

    // Create style flag object.
    StyleFlag flag;

    // Set style flag alignments true. It is the most crucial statement.
    // Because if it is false, no changes will take place.
    flag.SetAlignments(true);

    // Apply style to range of cells.
    rng.ApplyStyle(st, flag);

    // Save the workbook in XLSX format.
    wb.Save(outputDir + u"outputChangeCellsAlignmentAndKeepExistingFormatting.xlsx", SaveFormat::Xlsx);

    Aspose::Cells::Cleanup();
