The TH element or <TH> tag helps in identifying a table header. The text inserted using the TH element is in boldface and centred by default.
TD element or <TD> tag identifies the table data cell. TD element or the <td> tag is aligned to the left and the text is in regular font.
The attributes used with <TD> or <TH> tag are : Align, Colspan, No wrap, Rowspan, Valign.
The align attribute is similar to that of table, except that it align the text inside the cell rather than the table. Valign takes the value top, middle, bottom to vertically align the text inside a cell.
The Nowrap attribute does not allow the text to flow to the next line in the cell. If the sentence is wider than the width of the cell, nowrap will show the sentence in one straight line.
