What is the difference between “apex:dataTable” and “apex:pageBlockTable” components in Salesforce Visualforce?

Apex:dataTable – An HTML table that is defined by iterating over a set of data, displaying information about one item of data per row.  The data set can include up to 1,000 items.->no need to write inside <apex:pageblock> or <apex:pageblocksection>
-> there is no required value
-> the data can be displayed using custom styles
-> we need to specify column headers explicitly

Apex:pageBlockTable – A list of data displayed as a table within either an < apex:pageBlock > or < apex:pageBlockSection > component, similar to a related list or list view in a standard Salesforce page. Like an < apex:dataTable >, an < apex:pageBlockTable > is defined by iterating over a set of data, displaying information about one item of data per row. The set of data can contain up to 1,000 items.The body of the

< apex:pageBlockTable > contains one or more column components that specify what information should be displayed for each item of data, similar to a table. Unlike the < apex:dataTable > component, the default styling for < apex:pageBlockTable > matches standard Salesforce styles.
