Create HTML Table in Java

The HTML table is defined using the <table> element, and its structure is further specified using various other elements, such as <tr> for rows, <th> for header cells, and <td> for data cells.

We can easily create an HTML table by following the steps below:

  1. Create an instance of the HTMLDocument class.
  2. Optionally, create a style element and append it to the head element.
  3. Create <table>, <tbody>, <tr>, <th>, and <td> elements using the createElement() method.
  4. Append child elements to their parent elements using the appendChild() method.
  5. After that, append the <table> element to the <body> element.
  6. Finally, call the save() method to save the document at the given file path.

The following code sample shows how to create an HTML table in Java.

Create HTML Table With Style Attribute in Java

We can specify the <style> attributes for HTML elements using the SetAttribute(string name, string value) method. We will create an HTML table by following the steps mentioned earlier. However, we need to set the <style> attributes using the SetAttribute(string name, string value) method. It adds a new attribute for the element or updates the value if the attribute name is already present. We can set attributes for <table>, <tbody>, <tr>, <th>, and <td> elements.

The following code sample shows how to create an HTML table with style attributes in Java.

We can set <colspan> and <rowspan> attributes for table cells using the SetAttribute(string name, string value) method, as shown below:
