使用C ++在Word文檔中插入表格

可以通過幾個簡單的步驟在Word文檔中插入表格。但是，在此處需要注意的重要一點是，必須將文檔對象傳遞給每個節(jié)點的構(gòu)造函數(shù)，以便所有子節(jié)點都屬于同一對象。您需要按照以下步驟操作：

• 初始化Document類的對象
• 創(chuàng)建表對象
• 將表添加到文檔
• 創(chuàng)建行和列
• 在表格單元格上應(yīng)用自動寬度
• 保存輸出Word文檔

下面的代碼段顯示了如何使用C ++在Word文檔（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文檔中從HTML插入表格

HTML文件中可能包含需要插入到DOCX，DOC等Word文檔中的表格。或者您可能需要從網(wǎng)站復(fù)制表格。因此，您可以輕松地將HTML標記作為表格解析為Word文檔，而不必從頭開始創(chuàng)建和設(shè)計表格。例如，讓我們使用以下HTML字符串將表添加到word文檔中：

我們將內(nèi)容保持簡單，以便可以通過基本但重要的用例來演示對表標記的支持。此外，在此必須注意，不能將AutoFit應(yīng)用于從HTML創(chuàng)建的表。讓我們按照以下步驟在Word文檔中插入HTML表：

• 初始化Document類的實例
• 使用InsertHtml方法傳遞HTML標記
• 保存輸出DOCX字文件

下面的代碼遵循這些步驟，并顯示如何使用C ++在帶有HTML的Word文檔中創(chuàng)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);

此方法比我們上面探討的方法簡單一些。原因是，不需要為行，列或單元格一個接一個地添加每個節(jié)點，因為HTML字符串中的Table標記包含所有信息。以下是此簡單HTML表添加到Word文檔中的屏幕截圖：

在C ++中使用文檔生成器插入表

Aspose.Words for C ++ API的最好之處在于，它提供了多種功能，這些功能已成為API的競爭優(yōu)勢，并使其在其他選擇中脫穎而出。同樣，使用文檔構(gòu)建器插入表格的功能是在Word文檔（DOC / DOCX）中添加表格的另一種方法。因此，讓我們從三個不同的角度探討細節(jié)：

使用C ++在帶有Document Builder的DOCX中插入簡單表

要使用“文檔”構(gòu)建器在Word文檔中添加簡單表格，需要執(zhí)行以下步驟：

• 創(chuàng)建文檔對象
• 調(diào)用StartTable（）方法并插入單元格
• 添加行和單元格
• 保存輸出DOCX文件

此外，下面的代碼段顯示了如何使用C ++在DOCX文件中插入簡單表：

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 ++在帶有Document Builder的DOCX中插入格式化表格

可以將格式化的表格插入Word文檔中。此外，請按照以下步驟實現(xiàn)您的要求：

• 初始化Document類的實例
• 使標題行
• 設(shè)置縮進格式和功能
• 重置字體格式
• 保存輸出Word DOCX文件

下面的代碼片段使用C ++在DOCX文件中創(chuàng)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

有時我們需要在現(xiàn)有表內(nèi)添加另一個表。例如，表的某些行或列中的單元格可以包含子類別或某些其他字段的子表。在這種情況下，嵌套表很有用，可以按照以下步驟添加：

• 建立外部表，然后調(diào)用EndTable方法
• 在外部表的單元格內(nèi)建立內(nèi)部表
• 保存輸出的Word文檔

以下代碼段顯示了如何使用C ++在Word文檔中插入嵌套表：

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);
