使用php创建自动生成的表

Question

I am trying to create an auto generated table which is a part of a project I am trying to do. I am trying to create a duty roster for a group of 14 staff. The shifts are as follows :

Shift 1 : 4 staff Shift 2: 4 staff Shift 3: 4 staff Off duty: 2 staff

To ease this process I have assigned a number to each staff, starting from 1 to 14.

Here is the code so far, but it does not work just right.

 <table>
<tr>
    <th>Shift 1</th>
    <th>Shift 2</th>
    <th>Shift 3</th>
    <th>Off</th>
</tr>

@for ($i = 1; $i <= 30 ; $i++)
<tr>
    @for ($j = 1; $j <= 4 ; $j++)
        <th>
            @if ($j==1)
                @for ($h = 1; $h <= 4 ; $h++)
                    {{ $h }},
                @endfor
            @endif

            @if ($j==2)
                @for ($h = 5; $h <= 8 ; $h++)
                    {{ $h }},
                @endfor
            @endif

            @if ($j==3)
                @for ($h = 9; $h <= 12 ; $h++)
                    {{ $h }},
                @endfor
            @endif

            @if ($j==4)
                @for ($h = 13; $h <= 14 ; $h++)
                    {{ $h }},
                @endfor
            @endif

        </th>
    @endfor

</tr>

@endfor

The above code gives me a table as below :

The end goal is to produce something as below : Any help much appreciated. :)

You should do it in PHP and set to Blade only data to display because in blade it's hard to assign variables without modifications or hack.

This is what I did:

<table>
<tr>
    <th>Shift 1</th>
    <th>Shift 2</th>
    <th>Shift 3</th>
    <th>Off</th>
</tr>

{{-- */$last=1;/* --}}
@for ($i = 1; $i <= 30 ; $i++)
<tr>


    @for ($j = 0; $j < 14 ; ++$j)
      @if ($j %4 == 0)
        <th>
      @endif

        @if ($j + $last > 14)
          {{-- */$last= -$j + 1 ;/* --}}
        @endif
        {{ $j + $last }}
      @if ($j %4 == 3)
        </th>
      @endif

    @endfor

    </th>
{{-- */
    $last=$j + $last -2;
    if ($last > 14) {
        $last = 1;
    }
/* --}}


</tr>
@endfor

Output is as in below screen
