What's table?

Question

what's table (table data table row etc.) and what does it do?

Answer 1

A table is a set of rows and columns, whether it is in java, html, sql, or in mathematics.
In HTML,
there is a tag <table> used to create a table.
Since a collection of cells collectively form a table we need cells.
So we use <tr>
tag to create a row and insert any number of cells in it by
tag <td> means table data or
tag <th> which defines a header cell.
eg.
<table>
<tr>
<td>cell1</td>
<td>cell2</td>
</tr>
<tr>
<td>cell3</td>
<td>cell4</td>
</tr>
