表格有助于组织信息和数字。我们经常在Word文档（DOCX / DOC）中插入表格以显示信息。在文字处理应用程序中可以使用C ++轻松创建表。

Aspose.Words for C ++提供了几乎所有基本的和高级的Word自动化功能，并且可以积极地满足Qt应用程序中的Word处理要求。因此，让我们看看如何集成和利用我们的C ++ Word库在Qt应用程序中创建Word文档。

在本文中，将介绍如何使用C ++在Word文档中插入表格。包括以下内容：如果你还没有用过C ++版Aspose.Words可以点击这里下载最新版测试。

使用C ++在Word文档中插入表格

可以通过几个简单的步骤在Word文档中插入表格。但是，在此处需要注意的重要一点是，必须将文档对象传递给每个节点的构造函数，以便所有子节点都属于同一对象。您需要按照以下步骤操作：

• 初始化Document类的对象
• 创建表对象
• 将表添加到文档
• 创建行和列
• 在表格单元格上应用自动宽度
• 保存输出Word文档

下面的代码段显示了如何使用C ++在Word文档（DOCX / DOC）中插入表格：

// The path to the documents directory.
System::String outputDataDir = dataDir;
System::SharedPtr<Document> doc = System::MakeObject<Document>();

// We start by creating the table object. Note how we must pass the document object
// To the constructor of each node. This is because every node we create must belong
// To some document.
System::SharedPtr<Table> table = System::MakeObject<Table>(doc);

// Add the table to the document.
doc->get_FirstSection()->get_Body()->AppendChild(table);

// Here we could call EnsureMinimum to create the rows and cells for us. This method is used
// To ensure that the specified node is valid, in this case a valid table should have at least one
// Row and one cell, therefore this method creates them for us.
// Instead we will handle creating the row and table ourselves. This would be the best way to do this
// If we were creating a table inside an algorthim for example.
System::SharedPtr<Row> row = System::MakeObject<Row>(doc);
row->get_RowFormat()->set_AllowBreakAcrossPages(true);
table->AppendChild(row);

// We can now apply any auto fit settings.
table->AutoFit(AutoFitBehavior::FixedColumnWidths);

// Create a cell and add it to the row
System::SharedPtr<Cell> cell = System::MakeObject<Cell>(doc);
cell->get_CellFormat()->get_Shading()->set_BackgroundPatternColor(System::Drawing::Color::get_LightBlue());
cell->get_CellFormat()->set_Width(80);

// Add a paragraph to the cell as well as a new run with some text.
cell->AppendChild(System::MakeObject<Paragraph>(doc));
cell->get_FirstParagraph()->AppendChild(System::MakeObject<Run>(doc, u"Row 1, Cell 1 Text"));

// Add the cell to the row.
row->AppendChild(cell);

// We would then repeat the process for the other cells and rows in the table.
// We can also speed things up by cloning existing cells and rows.
row->AppendChild((System::StaticCast<Node>(cell))->Clone(false));
row->get_LastCell()->AppendChild(System::MakeObject<Paragraph>(doc));
row->get_LastCell()->get_FirstParagraph()->AppendChild(System::MakeObject<Run>(doc, u"Row 1, Cell 2 Text"));
System::String outputPath = outputDataDir + u"InsertTableDirectly.doc";

// Save the document to disk.
doc->Save(outputPath);

使用C ++在Word文档中从HTML插入表格

HTML文件中可能包含需要插入到DOCX，DOC等Word文档中的表格。或者您可能需要从网站复制表格。因此，您可以轻松地将HTML标记作为表格解析为Word文档，而不必从头开始创建和设计表格。例如，让我们使用以下HTML字符串将表添加到word文档中：

我们将内容保持简单，以便可以通过基本但重要的用例来演示对表标记的支持。此外，在此必须注意，不能将AutoFit应用于从HTML创建的表。让我们按照以下步骤在Word文档中插入HTML表：

• 初始化Document类的实例
• 使用InsertHtml方法传递HTML标记
• 保存输出DOCX字文件

下面的代码遵循这些步骤，并显示如何使用C ++在带有HTML的Word文档中创建表：

// The path to the documents directory.
System::String outputDataDir = dataDir;
System::SharedPtr<Document> doc = System::MakeObject<Document>();
System::SharedPtr<DocumentBuilder> builder = System::MakeObject<DocumentBuilder>(doc);

// Insert the table from HTML. Note that AutoFitSettings does not apply to tables
// Inserted from HTML.
builder->InsertHtml(u"<table><tr><td>Row 1, Cell 1</td><td>Row 1, Cell 2</td></tr><tr><td>Row 2, Cell 1</td><td>Row 2, Cell 2</td></tr></table>");

System::String outputPath = outputDataDir + u"InsertTableFromHtml.doc";
// Save the document to disk.
doc->Save(outputPath);

此方法比我们上面探讨的方法简单一些。原因是，不需要为行，列或单元格一个接一个地添加每个节点，因为HTML字符串中的Table标记包含所有信息。以下是此简单HTML表添加到Word文档中的屏幕截图：

在C ++中使用文档生成器插入表

Aspose.Words for C ++ API的最好之处在于，它提供了多种功能，这些功能已成为API的竞争优势，并使其在其他选择中脱颖而出。同样，使用文档构建器插入表格的功能是在Word文档（DOC / DOCX）中添加表格的另一种方法。因此，让我们从三个不同的角度探讨细节：

使用C ++在带有Document Builder的DOCX中插入简单表

要使用“文档”构建器在Word文档中添加简单表格，需要执行以下步骤：

• 创建文档对象
• 调用StartTable（）方法并插入单元格
• 添加行和单元格
• 保存输出DOCX文件

此外，下面的代码段显示了如何使用C ++在DOCX文件中插入简单表：

System::SharedPtrdoc = System::MakeObject();
System::SharedPtrbuilder = System::MakeObject(doc);

// We call this method to start building the table.
builder->StartTable();
builder->InsertCell();
builder->Write(u"Row 1, Cell 1 Content.");

// Build the second cell
builder->InsertCell();
builder->Write(u"Row 1, Cell 2 Content.");

// Call the following method to end the row and start a new row.
builder->EndRow();

// Build the first cell of the second row.
builder->InsertCell();
builder->Write(u"Row 2, Cell 1 Content");

// Build the second cell.
builder->InsertCell();
builder->Write(u"Row 2, Cell 2 Content.");
builder->EndRow();

// Signal that we have finished building the table.
builder->EndTable();
System::String outputPath = outputDataDir + u"InsertTableUsingDocumentBuilder.SimpleTable.doc";

// Save the document to disk.
doc->Save(outputPath);

使用C ++在带有Document Builder的DOCX中插入格式化表格

可以将格式化的表格插入Word文档中。此外，请按照以下步骤实现您的要求：

• 初始化Document类的实例
• 使标题行
• 设置缩进格式和功能
• 重置字体格式
• 保存输出Word DOCX文件

下面的代码片段使用C ++在DOCX文件中创建了格式表：

System::SharedPtrdoc = System::MakeObject();
System::SharedPtrbuilder = System::MakeObject(doc);
System::SharedPtrtable = builder->StartTable();

// Make the header row.
builder->InsertCell();

// Set the left indent for the table. Table wide formatting must be applied after
// At least one row is present in the table.
table->set_LeftIndent(20.0);

// Set height and define the height rule for the header row.
builder->get_RowFormat()->set_Height(40.0);
builder->get_RowFormat()->set_HeightRule(HeightRule::AtLeast);

// Some special features for the header row.
builder->get_CellFormat()->get_Shading()->set_BackgroundPatternColor(System::Drawing::Color::FromArgb(198, 217, 241));
builder->get_ParagraphFormat()->set_Alignment(ParagraphAlignment::Center);
builder->get_Font()->set_Size(16);
builder->get_Font()->set_Name(u"Arial");
builder->get_Font()->set_Bold(true);
builder->get_CellFormat()->set_Width(100.0);
builder->Write(u"Header Row,\n Cell 1");

// We don't need to specify the width of this cell because it's inherited from the previous cell.
builder->InsertCell();
builder->Write(u"Header Row,\n Cell 2");
builder->InsertCell();
builder->get_CellFormat()->set_Width(200.0);
builder->Write(u"Header Row,\n Cell 3");
builder->EndRow();

// Set features for the other rows and cells.
builder->get_CellFormat()->get_Shading()->set_BackgroundPatternColor(System::Drawing::Color::get_White());
builder->get_CellFormat()->set_Width(100.0);
builder->get_CellFormat()->set_VerticalAlignment(CellVerticalAlignment::Center);

// Reset height and define a different height rule for table body
builder->get_RowFormat()->set_Height(30.0);
builder->get_RowFormat()->set_HeightRule(HeightRule::Auto);
builder->InsertCell();

// Reset font formatting.
builder->get_Font()->set_Size(12);
builder->get_Font()->set_Bold(false);

// Build the other cells.
builder->Write(u"Row 1, Cell 1 Content");
builder->InsertCell();
builder->Write(u"Row 1, Cell 2 Content");
builder->InsertCell();
builder->get_CellFormat()->set_Width(200.0);
builder->Write(u"Row 1, Cell 3 Content");
builder->EndRow();
builder->InsertCell();
builder->get_CellFormat()->set_Width(100.0);
builder->Write(u"Row 2, Cell 1 Content");
builder->InsertCell();
builder->Write(u"Row 2, Cell 2 Content");
builder->InsertCell();
builder->get_CellFormat()->set_Width(200.0);
builder->Write(u"Row 2, Cell 3 Content.");
builder->EndRow();
builder->EndTable();
System::String outputPath = outputDataDir + u"InsertTableUsingDocumentBuilder.FormattedTable.doc";

// Save the document to disk.
doc->Save(outputPath);

使用C ++使用Document Builder在DOCX中插入嵌套表

有时我们需要在现有表内添加另一个表。例如，表的某些行或列中的单元格可以包含子类别或某些其他字段的子表。在这种情况下，嵌套表很有用，可以按照以下步骤添加：

• 建立外部表，然后调用EndTable方法
• 在外部表的单元格内建立内部表
• 保存输出的Word文档

以下代码段显示了如何使用C ++在Word文档中插入嵌套表：

System::SharedPtr<Document> doc = System::MakeObject<Document>();
System::SharedPtr<DocumentBuilder> builder = System::MakeObject<DocumentBuilder>(doc);

// Build the outer table.
System::SharedPtr<Cell> cell = builder->InsertCell();
builder->Writeln(u"Outer Table Cell 1");
builder->InsertCell();
builder->Writeln(u"Outer Table Cell 2");

// This call is important in order to create a nested table within the first table
// Without this call the cells inserted below will be appended to the outer table.
builder->EndTable();

// Move to the first cell of the outer table.
builder->MoveTo(cell->get_FirstParagraph());

// Build the inner table.
builder->InsertCell();
builder->Writeln(u"Inner Table Cell 1");
builder->InsertCell();
builder->Writeln(u"Inner Table Cell 2");
builder->EndTable();
System::String outputPath = outputDataDir + u"InsertTableUsingDocumentBuilder.NestedTable.doc";

// Save the document to disk.
doc->Save(outputPath);
