![]() The value that is returned from the function is whatever DataTables will use for the data being requested (display, ordering, search, etc). The original and full data object or array for the row.The data type being requested by DataTables - this allows the function to support orthogonal data.If columns.data is null, null will be the value given here. The data that is pointed to by columns.data.The function is passed in three parameters: Using columns.render is the most common method as it provides absolute control over the data that will be displayed to the end user (this is a regular Javascript function, so you can do virtually anything you wish with the data). As a string to select data from an object A display may be used to represent exploratory, basic, or initial data, or at the other end of the process of analysis, it could help in showing detailed or causal explanations, and it could even be used as a way of generating research hypotheses and developing theory ( Burke et al., 2005 Miles & Huberman, 1994 ).The columns.data method can be used to get and set data, but the set operation adds significant complexity and it is recommended that the columns.data option be used simply to point to the original representation of the data and allow a renderer ( columns.render), which is read only, to transform the data.Ĭolumns.render can be utilised in a number of different ways: The primary advantage of using a data renderer in DataTables is that you can modify the output data without modifying the original data. This transformation of the original data into the value that will be shown in the DataTable is called rendering in DataTables' terminology and is performed using the columns.render option. You may wish to transform it to a different representation (such as a time stamp into a human readable format), combine data points (first and last names, perhaps) or perform some computation on the value (maybe calculating margin from turnover and expense values). There are occasions when the data source for the table's rows does not contain the value that you would want to display in the table.
