jQuery实现冻结 固定 表格行和列
function freezeTable(table, freezeRowNum, freezeColumnNum, width, height) { if (typeof(freezeRowNum) == 'string') freezeRowNum = parseInt(freezeRowNum) if (typeof(freezeColumnNum) == 'string') freezeColumnNum = parseInt(freezeColumnNum) var tableId; if (typeof(table) == 'string') { tableId = table; table = $('#' + tableId); } else tableId = table.attr('id'); var divTableLayout = $("#" + tableId + "_tableLayout"); if (divTableLayout.length != 0) { divTableLayout.before(table); divTableLayout.empty(); } else { table.after("<div id='" + tableId + "_tableLayout' style='overflow:hidden;height:" + height + "px; width:" + width + "px;'></div>"); divTableLayout = $("#" + tableId + "_tableLayout"); } var html = ''; if (freezeRowNum > 0 && freezeColumnNum > 0) html += '<div id="' + tableId + '_tableFix" style="padding: 0px;"></div>'; if (freezeRowNum > 0) html += '<div id="' + tableId + '_tableHead" style="padding: 0px;"></div>'; if (freezeColumnNum > 0) html += '<div id="' + tableId + '_tableColumn" style="padding: 0px;"></div>'; html += '<div id="' + tableId + '_tableData" style="padding: 0px;"></div>'; $(html).appendTo("#" + tableId + "_tableLayout"); var divTableFix = freezeRowNum > 0 && freezeColumnNum > 0 ?
