At their most basic, tables are made up cells, arranged into rows. You can control display characteristics for the whole table, for individual rows, and for individual cells.
<table border="1px" style="width:300px">
<thead>
<tr>
<th>First Name</th>
<th>Last Name</th>
<th>Age</th>
</tr>
</thead>
<tbody>
<tr>
<td>Jill</td>
<td>Smith</td>
<td>50</td>
</tr>
<tr>
<td>Eve</td>
<td>Jackson</td>
<td>94</td>
</tr>
<tr>
<td>John</td>
<td>Doe</td>
<td>80</td>
</tr>
</tbody>

A table cell in HTML is a non-empty element and should always be closed. There are two different kinds of table cell in HTML: normal table cell and header cell. <td> denotes a table cell, the name implying 'data', while <th> denotes a table 'header'. The two can be used interchangeably, but it is recommended that header cell be only used for the top and side headers of a table.
A table cell also must be nested within a <table> tag and a <tr> (table row) tag. If there are more table cell tags in any given row than in any other, the particular <tr> must be given a colspan attribute declaring how many columns of cells wide it should be.
An example of an HTML table containing 4 cells:
| Cell 1 | Cell 2 |
| Cell 3 | Cell 4 |
(2) Data Type
A data type must be specified for each column & for each attributes compromising on abstract data type. They are classifieed broadly as pre-defined data type.
<!DOCTYPE html><html><body><table border="1" cellspacing="0"><tr><th rowspan="2"> One</th><th colspan="2">Two</th></tr><tr><td>Three</td><td>Four</td></tr></table></body></html>
output:-
| One | Two | |
|---|---|---|
| Three | Four | |
Responsive web design (RWD) is an approach to web design that makes web pages render well on a variety of devices and window or screen sizes from minimum to maximum display size.
Components of Responsive Web Design (RWD):-
To create a responsive website, add the following <meta> tag to all your web pages:
<meta name="viewport" content="width=device-width, initial-scale=1.0">
This will set the viewport of your page, which will give the browser instruction on how to control the page's dimensions and scaling.
Responsive images are images that scale nicely to fit any browser size.
To make an image responsive, you need to give a new value to its width property. Then the height of the image will adjust itself automatically. The important thing to know is that you should always use relative units for the width property like percentage, rather than absolute ones like pixels.In addition to resize text and images, it is also common to use media queries in responsive web pages.
With media queries you can define completely different styles for different browser sizes.
The text size can be set with a "vw" unit, which means the "viewport width".
HTML table tag is used to display data in tabular form (row * column). There can be many columns in a row.
We can create a table to display data in tabular form, using <table> element, with the help of <tr> , <td>, and <th> elements.
In Each table, table row is defined by <tr> tag, table header is defined by <th>, and table data is defined by <td> tags.
HTML tables are used to manage the layout of the page e.g. header section, navigation bar, body content, footer section etc. But it is recommended to use div tag over table to manage the layout of the page .
| Tag | Description |
|---|---|
| <table> | It defines a table. |
| <tr> | It defines a row in a table. |
| <th> | It defines a header cell in a table. |
| <td> | It defines a cell in a table. |
| <caption> | It defines the table caption. |
| <colgroup> | It specifies a group of one or more columns in a table for formatting. |
| <col> | It is used with <colgroup> element to specify column properties for each column. |
| <tbody> | It is used to group the body content in a table. |
| <thead> | It is used to group the header content in a table. |
| <tfooter> | It is used to group the footer content in a table. |
The rowspan and colspan are <td> tag attributes. These are used to specify the number of rows or columns a cell should span. The rowspan attribute is for rows as well as the colspan attribute is for columns.
Syntax:- <td rowspan="number">
where 'number' specifies the no. of rows a cell should span.
Syntax:- <td colspan="number">
where 'number' specifies the no. of column a cell should span.
