* Maintenance of web-sites can often cause unexpected headaches, particularly
|
|
* if the hardcoded index of an array (the columns in a DataTables instance)
|
|
* needs to change due to an added or removed column. This plug-in function
|
|
* will match a given string to the title of a column in the table and return
|
|
* the column index, helping to overcome this problem.

* @name fnGetColumnIndex

* @summary Get the column index by searching the column titles

|
* @param {string} sCol Column title to search for
|
|
* @returns {integer} Column index, or -1 if not found
