HTML Tags Inside Table In PDF File
In this tutorial, we are going to learn how to use HTML tags inside a table in a PDF document using Aspose.PDF for .NET. We will explain the source code in C# step by step. At the end of this tutorial, you will know how to insert HTML content into a table in a PDF document. Let’s start!
Step 1: Setting up the environment
Make sure you have configured your C# development environment with Aspose.PDF for .NET. Add the reference to the library and import the necessary namespaces.
Step 2: Creating table data
We create a DataTable containing a “data” column of type String. We then add rows to this DataTable using HTML content.
DataTable dt = new DataTable("Employee");
dt.Columns.Add("data", System.Type.GetType("System.String"));
DataRow dr = dt.NewRow();
dr[0] = "<li>Department of Emergency Medicine: 3400 Spruce Street Ground Silverstein Bldg Philadelphia PA 19104-4206</li>";
dt.Rows.Add(dr);
dr = dt. NewRow();
dr[0] = "<li>Penn Observation Medicine Service: 3400 Spruce Street Ground Floor Donner Philadelphia PA 19104-4206</li>";
dt.Rows.Add(dr);
dr = dt. NewRow();
dr[0] = "<li>UPHS/Presbyterian - Dept. of Emergency Medicine: 51 N. 39th Street . Philadelphia PA 19104-2640</li>";
dt.Rows.Add(dr);
Step 3: Creating the Document and Table
We create a new PDF document and add a page in this document. Next, we initialize an instance of the Table class and set the table properties.
Document doc = new Document();
doc.Pages.Add();
Aspose.Pdf.Table tableProvider = new Aspose.Pdf.Table();
tableProvider. ColumnWidths = "400 50";
tableProvider.Border = new Aspose.Pdf.BorderInfo(Aspose.Pdf.BorderSide.All, 0.5F, Aspose.Pdf.Color.FromRgb(System.Drawing.Color.LightGray));
tableProvider.DefaultCellBorder = new Aspose.Pdf.BorderInfo(Aspose.Pdf.BorderSide.All, 0.5F, Aspose.Pdf.Color.FromRgb(System.Drawing.Color.LightGray));
Aspose.Pdf.MarginInfo margin = new Aspose.Pdf.MarginInfo();
margin. Top = 2.5F;
margin. Left = 2.5F;
margin. Bottom = 1.0F;
tableProvider. DefaultCellPadding = margin;
Step 4: Importing data into the table
We import the data from the DataTable into the table using the “ImportDataTable” method. We specify method parameters to indicate which range of rows and columns of the DataTable should be imported.
tableProvider.ImportDataTable(dt, false, 0, 0, 3, 1, true);
Step 5: Adding the table to the document
We add the table to the document page.
doc.Pages[1].Paragraphs.Add(tableProvider);
Stage 6: Saving the document
We save the PDF document with the table containing HTML content.
doc.Save(dataDir + "HTMLInsideTableCell_out.pdf");
Example source code for HTML Tags Inside Table using Aspose.PDF for .NET
// The path to the documents directory.
string dataDir = "YOUR DOCUMENT DIRECTORY";
DataTable dt = new DataTable("Employee");
dt.Columns.Add("data", System.Type.GetType("System.String"));
DataRow dr = dt.NewRow();
dr[0] = "<li>Department of Emergency Medicine: 3400 Spruce Street Ground Silverstein Bldg Philadelphia PA 19104-4206</li>";
dt.Rows.Add(dr);
dr = dt.NewRow();
dr[0] = "<li>Penn Observation Medicine Service: 3400 Spruce Street Ground Floor Donner Philadelphia PA 19104-4206</li>";
dt.Rows.Add(dr);
dr = dt.NewRow();
dr[0] = "<li>UPHS/Presbyterian - Dept. of Emergency Medicine: 51 N. 39th Street . Philadelphia PA 19104-2640</li>";
dt.Rows.Add(dr);
Document doc = new Document();
doc.Pages.Add();
// Initializes a new instance of the Table
Aspose.Pdf.Table tableProvider = new Aspose.Pdf.Table();
//Set column widths of the table
tableProvider.ColumnWidths = "400 50 ";
// Set the table border color as LightGray
tableProvider.Border = new Aspose.Pdf.BorderInfo(Aspose.Pdf.BorderSide.All, 0.5F, Aspose.Pdf.Color.FromRgb(System.Drawing.Color.LightGray));
// Set the border for table cells
tableProvider.DefaultCellBorder = new Aspose.Pdf.BorderInfo(Aspose.Pdf.BorderSide.All, 0.5F, Aspose.Pdf.Color.FromRgb(System.Drawing.Color.LightGray));
Aspose.Pdf.MarginInfo margin = new Aspose.Pdf.MarginInfo();
margin.Top = 2.5F;
margin.Left = 2.5F;
margin.Bottom = 1.0F;
tableProvider.DefaultCellPadding = margin;
tableProvider.ImportDataTable(dt, false, 0, 0, 3, 1, true);
doc.Pages[1].Paragraphs.Add(tableProvider);
doc.Save(dataDir + "HTMLInsideTableCell_out.pdf");

FAQs for HTML tags inside table in PDF file
Q: Can I use other HTML tags and attributes inside the table cells?
A: Yes, you can use various HTML tags and attributes inside the table cells, such as <b>, <i>, <a>, and many more. Aspose.PDF for .NET supports a wide range of HTML elements and styles that you can use to format the content within the table cells.
Q: Can I apply CSS styles to the HTML content inside the table cells?
A: Yes, you can apply CSS styles to the HTML content inside the table cells. Aspose.PDF for .NET provides support for basic CSS styles that can be applied to the HTML elements.
Q: Is it possible to add images along with HTML content inside the table cells?
A: Yes, you can add images along with HTML content inside the table cells. You can use HTML <img> tags to include images from various sources, such as local files or URLs.
Q: How can I specify different column widths for the table?
A: You can specify different column widths for the table using the ColumnWidths property of the table. The property takes a string containing space-separated values, where each value represents the width of a column in points.
Q: Can I use nested tables inside a cell with HTML content?
A: Yes, you can use nested tables inside a cell with HTML content. You can create separate table instances and add them as part of the HTML content inside a cell to achieve the nesting effect.
