TR(<tr></tr> tag ) stands for Table Row and used to insert rows in the table. Data in html tables are inserted into rows. The basic building blocks of an html table is the table row. A table row doesn't contain any data directly. the <tr> tag defines a row in a html table and <tr> element contains one or more <th> or <td> element . These <th> and <td> contains the table date.

3) TH Tag
Table heading can be defined using <th> tag.
We use this tag when we need to write some heading text in table column, so it replace the <td> tag with <th>. Normally you will put your top row as table heading as shown below, so you use <th> element in first row. Heading which are defined in <th> tag are centered align align and bold by default.
Program
<! Doctype html>
<html>
<table border= 2>
<tr>
<th>A </th>
<th>Heading</th>
<th>Row</th></th>
<tr>
<td>The first</td>
<td>row of </td>
<td>table data</td></tr>
</tr>
<td>the second</td>
<td>row of</td>
<td>table date</td>
</td></table>
</html>

4) TD Tag
The <td> tag defines a standard cell or column in an html table. This tag must be nested inside a <tr> tag. The information contain this element is the left- aligned by default. We can say that column is necessary for the completion of table in html. There is a one column either <td> or <th> is must even for single row.
Program
