This feature is available since BellaDati 2.9.4

It is possible to define a custom renderer which will be used to display a specific chart or table. This renderer is defined in an extension. The user then has the option to select the renderer in chart appearance or table appearance settings.

Extension structure

  • Empty HTML head and HTML body 
  • Resources
    • table-renderer.js implementing rendeTable_ext(containerDiv, tableJSON) function
    • table-styles.js defining styles of the table

Content of table-renderer.js

Javascript responsible for rendering HTML content of the table. Function takes two parameters containerDiv selector and tableJSON holding JSON table data produced by BellaDati (see Report API).

var renderTable_ext#EXT_ID# = function(containerDiv, tableJSON) {
  var data = tableJSON.data;
  containerDiv.empty();
  
  // create TABLE inside containerDiv
  var table = $("<table></table>");
  table.addClass("bd-table_ext#EXT_ID#");
  containerDiv.append(table);

  // create THEAD inside TABLE
  var thead = $("<thead></thead>");
  thead.appendTo(table);
  // iterate over all rows in header
  for (i = 0; i < data.header.length; i++) {
    // insert new row into THEAD
    var theadRow =  $("<tr></tr>");
    theadRow.appendTo(thead);
    // iterate over all cells in a row
    var columns = data.header[i];
    for (j = 0; j < columns.length; j++) {
      var column = columns[j];
      if (column) {
        // insert new TH with value
        var theadCell = $("<th></th>");
        theadCell.appendTo(theadRow);
        theadCell.append(column.value);
        // set colspan/rowspan attributes
        if (typeof column.colspan != 'undefined') {
          theadCell.attr('colspan', column.colspan);
        }
        if (typeof column.rowspan != 'undefined') {
          theadCell.attr('rowspan', column.rowspan);
        }
      }
    }
  }

  // create TBODY inside TABLE
  var tbody = $("<tbody><tbody>");
  tbody.appendTo(table);
  // iterate over all rows in body
  for (i = 0; i < data.body.length; i++) {
    // insert new TR inside TBODY
    var tbodyRow = $("<tr></tr>");
    tbodyRow.appendTo(tbody);
    // iterate over all cells in a row
    var columns = data.body[i];
    for (j = 0; j < columns.length; j++) {
      var column = columns[j];
      if (column) {
        // insert new TD
        var tbodyCell = $("<td></td>");
        tbodyCell.appendTo(tbodyRow);
        tbodyCell.append(column.value);

        // set colspan/rowspan attributes
        if (typeof column.colspan != 'undefined') {
          tbodyCell.attr('colspan', column.colspan);
        }
        if (typeof column.rowspan != 'undefined') {
          tbodyCell.attr('rowspan', column.rowspan);
        }
      }
    }
  }
}
