Question

这与我们在学校完成的小组项目有关。我们的框架是codeigniter。

SELECT *  
FROM projects, task 
WHERE projects.projectname = task.projectname

上面的sql语句合并项目表和任务表，其中一个项目有很多任务。用表格显示上述sql语句的结果。此表有4列作为项目名称，客户端，任务，任务相关员工。由于项目具有许多任务项目名称和客户端在每个表记录中重复。我们想要做的只展示一次这个项目名称和客户端，并在其下显示任务。我怎样才能做到这一点？这是我们的观看代码

<table class="table table-lg" id="Table">
                <thead >
                    <tr class="filters">
                        <th ><input type="text" class="form-control" placeholder="Project" disabled></th>

                        <th><input type="text" class="form-control" placeholder="Client " disabled></th>
                        <th><input type="text" class="form-control" placeholder="Project Start On" disabled></th>
