Your javascript becomes simply $("table").DataTables(); and you're able to customize the display for every table within in the HTML; IE. if you have second, smaller table in the same page that should be limited to 10 rows, <table data-page-length="10">
you have to download the bootstrap-table.min.js and make some modification to it..
If you download the bootstrap-table.min.js, just open it, and try to find "pageList:[10,"
make it as "pageList:[10,15,20,25,50,100,"All"]" make sure that "All" written as this.
Default page size can be changed as well from the same line "pageSize:10" you can change it as pageSize:"All".
Other options can be modified as well.
Don't forget to include it or linked to new place after completed your modification.
