//Get cell instance from the table.

ICell cell1 = table.Rows[0].Cells[0];

//Add paragraph to add text content.

IParagraph paragraph1 = cell1.TextBody.AddParagraph();

//Add text part to the paragraph

ITextPart textPart1 = paragraph1.TextParts.Add();

//set value for the text content.

textPart1.Text = "Style1";

//Enable bold option.

textPart1.Font.Bold = true;

//Choose caps type of the text.

textPart1.Font.CapsType = TextCapsType.Small;

//set color to the text.

textPart1.Font.Color = ColorObject.CadetBlue;

//Set font style using font name.

textPart1.Font.FontName = "Times New Roman";
