Table Overview
Aspose.Words is a class library designed for server-side processing of documents in various formats – PDF, HTML, different Microsoft Word formats and others – and supports tables in the following ways:
- tables in a document are preserved during open/save and conversions
- it is possible to edit table, content, and its formatting, and then export the changes to a file in a format that supports tables
In this article, we will learn more about table structure, cells, rows, and columns supported by Aspose.Words, and the details of working with such tables.
Table Structure
As already mentioned, the table consists of such elements as Cell, Row and Column. These are concepts that are common to all tables in general, regardless of the document format.
This is a common example of a table found in a Microsoft Word document:
Table Nodes
A table from any document loaded into Aspose.Words is imported as a Table node. The table can be found as a child of:
- main text
- an inline story such as a comment or a footnote
- cells when a table is nested within another table
Table Content
The table node does not contain any real content – instead, it is a container for other such nodes that make up the content:
- Table contains many Row nodes. The table provides all the usual node elements, allowing you to freely move, modify, and remove the table in the document.
- Row represents a single table row and contains many Cell nodes. In addition, the Row provides elements that define how the row is displayed, such as height and alignment.
- Cell is what contains the true content visible in the table and is made up of a Paragraph and other block level nodes. Additionally, cells can contain nested tables.
Empty Paragraph after Table
The picture above shows that the document contains a table of several rows, which in turn consists of two cells. Each of the two cells includes a paragraph, which is the container for the cell’s formatted text.
It is also worth noting that separating two consecutive tables in a document requires at least one empty paragraph after the table. Without such a paragraph, consecutive tables would be joined together into one. This behavior is identical in both Microsoft Word and Aspose.Words.
Aspose.Words has a number of classes related to tables – Tables, Rows, Cells, and others.
