As of v2.15,
- A new filter widget filter_external option has been added that essentially does the same thing as the $.tablesorter.bindSearch function.
- To change an input from searching one column (or all columns) to search any other column, call the $.tablesorter.bindSearch function to update the external inputs, even if the inputs are set using the filter_external option. Pass an additional false flag as the last parameter to force the inputs to update.
```
$.tablesorter.bindSearch( $('table'), $('.search'), false );
```
- This demo shows how to use multiple external search filters to filter the table, and how to make one input dynamically change to filter any or all columns.
The $.tablesorter.filter.bindSearch function allows binding multiple external search filters
The advantage of using this function over your own is:
- Inputs behave the same as internal filters; searches adhere to the filter_liveSearch and filter_searchDelay options.
- When pressing the Esc key, the filter resets.
Include a data-column="#" attribute to specify to which column the search should apply; or data-column="all" to search all columns.
