本文主要介紹在使用Handsontable過程當中,對加載的數據進行字體顏色、樣式(style)、數據格式化,對齊方式的處理,並添加自定義圖片和單機事件功能。css
代碼以下:html

//若是要添加其餘樣式,能夠用如下寫法
//td.style = 'font-weight: bold;'; } else if (prop == 'price') { //格式化價格數據 td.innerText = value != null ? numbro(value).format('0.00') : ""; } else if (prop == 'sales') { //右對齊 td.style.textAlign = 'right'; td.innerText = value != null ? numbro(value).format('0,0.00') : ""; } else if (prop == 'del') { //添加自定義的圖片,並給圖片的chick添加事件 var escaped = Handsontable.helper.stringify(value), imgdel; imgdel = document.createElement('IMG'); imgdel.src = "handsontable/remove.png"; imgdel.width = 20; imgdel.name = escaped; imgdel.style = 'cursor:pointer;';//鼠標移上去變手型 Handsontable.dom.addEvent(imgdel, 'click', function (event) { hot.alter("remove_row", row);//刪除當前行 }); Handsontable.dom.empty(td); td.appendChild(imgdel); td.style.textAlign = 'center';//圖片居中對齊 return td; } } Handsontable.renderers.registerRenderer('negativeValueRenderer', negativeValueRenderer); var hot = new Handsontable(document.getElementById('example'),{ data: data, colHeaders: ['操做', '日期', '地點', '商品', '單價', '銷量'], // 使用自定義列頭 rowHeaders: true, colWidths: 150, // 設置全部列寬爲150像素 filters: true, columnSorting: true, sortIndicator: true, autoColumnSize: true, manualColumnResize: true, undo: true, redo: true, wordWrap: true, copyable: true, mergeCells: false, manualRowResize: true, manualRowMove: true, manualColumnMove: false, renderAllRows: true, allowInsertRow: true, allowInsertColumn: false, fixedColumnsLeft: 1, columns: [ { data: 'del', type: 'text' }, { data: 'riqi', type: 'date', dateFormat: 'YYYY-MM-DD' },{ data: 'address', type: 'text' },{ data: 'goods', type: 'text' },{ data: 'price', type: 'numeric' },{ data: 'sales', type: 'numeric' }], contextMenu: ['row_above', 'row_below', '---------', 'remove_row','---------','undo','redo','---------','make_read_only','---------','alignment'], dropdownMenu: ['filter_by_condition', 'filter_by_value', 'filter_action_bar'], cells: function (row, col, prop) { var cellProperties = {}; cellProperties.renderer = "negativeValueRenderer"; return cellProperties; }, }); </script> </body> </html>
須要注意的是在Handsontable中,colHeaders與columns須要一一對應,數據是根據columns中設置的前後順序加載的,效果以下:jquery
若是contextMenu和dropdownMenu不須要原來組件提供的那麼多選項,能夠像代碼中那樣寫,Handsontable也提供重寫方法,能夠參考官網:http://docs.handsontable.com/0.16.1/demo-context-menu.htmlapp
