Search

The columns.data and columns.render properties work together. Basically

You need to use the column() part to select the column to filter, and then the search() part to tell it what to search for. The column().search() documentation has details and examples of this. Allan

Hi, Thanks for putting up the code. As I mentioned above, you'd need to enabled regex using the second and third parameters of column().search(). Allan

With client-side processing you can use search() or column().search() as the built in string searching solutions. If you need something more complex you can create a custom search plug-in. Allan

If you are going to destroy the table, you probably want to call destroy() before you do the empty. However, you do you need to that? Can you not just use search() or column().search() to set the filters? Allan

Use columns.render to provide the calculation result before you do the export.

Use the columns.render option. There is an example in that options' documentation on how to display an image. Allan

I just reused the column.search() function once the table

If the id is in a column, then you would use column().search() on that column. Is it in a column? If not, you would need to put it into one. Allan

the table or use columns.render to create one. Allan
