Implementation of fixed table headers in a responsive table to respond to table Headers When data is displayed, the header is fixed for better readability. I. Implementation Method:1. Define two tables with a fixed absolute 2. Copy Table 1 var th_new=$("#table1 tr").eq(0).clone();$("#fixed-table1").append(th_new); 3. The resize () method is used to obtain the function trResize(){$("#fixed-table1 th").eac
