How to Merge Cells in HTML and WordPress

How to Merge Cells in HTML and WordPress

A data table with many cells next to each other can seem crammed. Some people don’t mind this kind of data presentation, while others would rather know how to merge cells in HTML.

By merging cells in a table, one can present many pieces of data in one large cell. This process often results in a large cell being displayed horizontally, vertically, or both over many rows or columns.

When the cells of a table span multiple rows, this is called “row-spanning.” When table cells span multiple columns, it is called “column-spanning” or a “colspan.”

This is mainly for presentation or reporting purposes to make a spreadsheet visually appealing. This article discusses how to merge cells in HTML and the WordPress working environment.

How to Merge Table Cells in HTML

The colspan attribute can fuse multiple table cells in a column in an <td> HTML tag (table data). When merging multiple row cells, one can use the rowspan attribute. Both of these attributes will be in the <td> tag.

The following examples show how to use these attributes in HTML and how they appear in the browser.

How to Use the Rowspan Attribute

This attribute determines how many rows a merged cell should span vertically. It can create a large vertical cell from two or more cells that occupy the same column, then display this in multiple rows.

For instance, the code <td rowspan=2 > merges two cells to create one large vertically positioned cell.

An HTML Table Code Example That Uses the Rowspan Attribute

The following code originates from a table with three columns and three rows. One can use the rowspan=”2″ attribute in the first <td> tag to create a single cell from the first two cells of the first column.

The number in the rowspan attribute determines the number of cells used for the <td> tag.

The following is an HTML table code example with a cell that stretches across two rows. To better understand how this code works, feel free to create a visual rendering in a browser.

<table>

<tr>
<td rowspan="2">&nbsp;</td>
<td>&nbsp;</td>
<td>&nbsp;</td>
</tr>

<tr>
<td>&nbsp;</td>
<td>&nbsp;</td>
</tr>

<tr>
<td>&nbsp;</td>
<td>&nbsp;</td>
<td>&nbsp;</td>
</tr>

</table>

Rendering this code in a browser will create a table with a large cell that spans the height of two rows. Changing the rowspan value to 3 will cause the first cell to span the height of all three rows.

When expanding a <td> row be sure to delete <td> tags from the other table rows (<tr>). When the first cell spans all three rows, there are only two <td> tags in the other two <tr> tags.

How to Use the Colspan Attribute

This attribute determines how many columns a merged cell will span horizontally. It creates a large horizontal cell from two or more cells that occupy the same row, then positions this across multiple columns.

Essentially, the colspan attribute defines the number of columns displayed across a large row. For instance, the HTML code <td colspan=2 > will merge two cells and create one large horizontal cell.

Two HTML Table Code Examples That Use the Colspan Attribute

The following code is an HTML table with a large cell that stretches across two columns. To better understand how this code works, feel free to create a visual rendering in a browser.

<table>

<tr>
<td colspan="2">&nbsp;</td>
<td>&nbsp;</td>
</tr>

<tr>
<td>&nbsp;</td>
<td>&nbsp;</td>
<td>&nbsp;</td>
</tr>

<tr>
<td>&nbsp;</td>
<td>&nbsp;</td>
<td>&nbsp;</td>
</tr>

</table>

Rendering this code in a browser will create a table with a large cell that spans the width of two columns. Changing the colspan attribute value to 3 will cause the first cell to span the width of all three columns.

When all 3 columns are crossed, there should only be one <td> in the table row ( <tr> ). So, be sure to remove any remaining <td> tags when expanding a <td> column.

Here is another example of an HTML table with a cell that stretches across two columns. To better understand the code, create a visual rendering in your browser via your computer’s notepad.

<table>

<tr>
<th>Month</th>
<th>Savings</th>
</tr>

<tr>
<td>January</td>
<td>$100</td>
</tr>

<tr>
<td>February</td>
<td>$80</td>
</tr>

<tr>
<td colspan="2">Sum: $180</td>
</tr>

</table>

How to Use “0” (Zero) in the Rowspan and Colspan Attributes

When used in the colspan and rowspan in a modern browser, “0” represents the most columns or rows. For instance, one can use rowspan=”0″ to extend a row to the end of a table instead of tallying the rows of the table.

What are the best tables to use zero in? The number zero is especially suitable for dynamic tables. It is also ideal for large tables with frequently changing numbers of columns and rows.
