Page break workaround (javascript) for chrome

Question

So, as known, this awesome CSS properties:

  table { page-break-inside:auto }
  tr    { page-break-inside:avoid; page-break-after:auto }
  thead { display:table-header-group }
  tfoot { display:table-footer-group }

Doesnt work on Chrome. So now comes the workaround. I have this table structure (please note JSP and EL syntax)

    <table class="table resultTable">
        <thead class="repeat">
            <tr class="head">
                <th>XPTO HEADER</th>
                <th>XPTO HEADER</th>
            </tr>
        </thead>
        <tbody>
            <c:forEach items="${items}" var="t" varStatus="loop">
                <tr>                        
                    <td class="money">${t.XPTO}</td>
                    <td class="money">${t.XPTO2}</td>
                </tr>
                <c:if test="${(loop.index + 1) % 20 == 0}">
                    <tr class="break-page">
                    </tr>                   
                </c:if>
            </c:forEach>                                        
        </tbody>
    </table>

Two things to notice: the class "repeat" on the thread and the empty tr with break-page class after 20 rows.

So, check this CSS:

    @media print {          
        .break-page {
             display: block; page-break-before: always;
        }
    }

And check this JS:

     var repeat = $('.repeat tr');

     $('.break-page').after(repeat.clone());

That's awesome :) This produces exactly what I want. Check how this first page:

And the second page, you can see that the header repeats, but, check out this huge white space:

So that's it. Can you guys help me get rid of that huge white space? Also I hope this helps if someone is having the same trouble as I am.

Thank you

Answer 1

All I did was: used div instead of table tag. Also I inserted a page-break after 20 rows for chrome. Created a javascript hack to add the header again.

NOTE: this creates different pages and data layout for each browser. Chrome has 3 pages and the last one the table is kinda in the middle... And firefox has only two pages, that fits perfectly. That was the best I could do.

HTML

            <div class="divTable">
                <div class="divHeading">
                    <div class="divCell">${i18n.label.initialValue}</div>
                    <div class="divCell">${i18n.label.additions}</div>
                    <div class="divCell">${i18n.label.discounts}</div>
                    <div class="divCell">${i18n.label.finalValue}</div>
                </div>
                <c:forEach items="${detailedCashFlow.transactions}" var="t" varStatus="loop">
                        <div class="divCell money">${t.initialValue}</div>
                        <div class="divCell money">${t.totalAddition}</div>
                        <div class="divCell money">${t.totalDiscount}</div>
                        <div class="divCell money">${t.value}</div>
                    </div>

                    //THIS IS VERY IMPORTANT
                    <c:if test="${fn:length(detailedCashFlow.transactions) > (loop.index + 1 ) && (loop.index + 1) % 20 == 0}">
                        <div class="break-page"></div>
                    </c:if>
                </c:forEach>                                        
            </div>

CSS

            .divTable
            {
                display: table;
                width: 100%;
                margin-top: 20px;
            }
            .divTitle
            {
                display: table-caption;
                text-align: center;
                font-weight: bold;
                font-size: larger;
            }
            .divHeading
            {
                display: table-row;
                font-weight: bold;
                text-align: center; 
            }
            .divRow
            {
                display: table-row;
            }
            .divCell
            {
                display: table-cell;
                border: solid;
                border-width: thin;
                padding-left: 5px;
                padding-right: 5px;
                text-align: center;         
                font-size: 12px;
            }
            .divRow:nth-child(even){
                background: #aad4ff !important;
            }
            .divRow:nth-child(odd){
                background: #FFF !important;
            }

            @media print {                        
                .divHeading { 
                    display:table-header-group;
                }

                .divRow
                {
                    -webkit-column-break-inside: avoid;
                    webkit-page-break-inside:avoid; 
                    page-break-inside:avoid; page-break-after:auto;    
                }

                .break-page {
                    page-break-before: always;
                }
            }

JS HACK

     var is_chrome = window.chrome;

     if(is_chrome){
         var repeat = $('.divHeading');

         $('.break-page').after(repeat.clone());             
     }
