Trabalhando com Tabela em PDFs Marcados

Criar Tabela em PDF Marcado

Aspose.PDF for .NET permite criar uma tabela em documentos PDF marcados. Para trabalhar com tabelas, a API fornece a classe TableElement. Para criar uma tabela, você pode usar o método CreateTableElement() da interface ITaggedContent. Além disso, você pode usar os métodos CreateTHead(), CreateTBody() e CreateTFoot() da classe TableElement para criar o Cabeçalho da Tabela, o Corpo da Tabela e o Rodapé da Tabela, respectivamente. Para criar uma linha de tabela, você pode usar o método CreateTR() da classe TableRowCollectionElement. Você também pode verificar se o documento PDF criado está em conformidade com PDF/UA usando o método Validate() da classe Document.

O seguinte trecho de código também funciona com a biblioteca Aspose.PDF.Drawing.

O seguinte trecho de código mostra como criar uma tabela no documento PDF marcado:

Estilizar Elemento da Tabela

Aspose.PDF for .NET permite estilizar uma tabela em documento PDF marcado. Para estilizar uma tabela, você pode criar uma tabela usando o método CreateTableElement() da interface ITaggedContent e definir o estilo da tabela usando as propriedades da classe TableElement. A seguir está a lista de propriedades que você pode usar para estilizar uma tabela:

Estilizar Linha da Tabela

Aspose.PDF for .NET permite estilizar uma linha de tabela em documento PDF marcado. Para estilizar uma linha de tabela, você pode usar as propriedades da classe TableTRElement. A seguir está a lista de propriedades que você pode usar para estilizar uma linha de tabela:

BackgroundColor.
