<li>a filtered Model (DataView) as a data source instead of a simple array</li>
<li>grid reacting to model events (onRowCountChanged, onRowsChanged)</li>
<li><b>FAST</b> DataView recalculation and <b>real-time</b> grid updating in response to data changes.<br/>The grid holds <b>50'000</b> rows, yet you are able to sort, filter, scroll, navigate and edit as if it had 50 rows.</li>
<li>adding new rows, bidirectional sorting</li>
<li>column options: cannotTriggerInsert</li>
<li>events: onCellChange, onAddNewRow, onKeyDown, onSelectedRowsChanged, onSort</li>
<li><font color=red>NOTE:</font> all filters are immediately applied to new/edited rows</li>
<li>Handling row selection against model changes.</li>
<li>Paging.</li>

我认为最简单的方法是只添加您希望在＆＃34;列＆＃34;中显示的3列。变量
如果您想稍后显示更多列，可以动态添加更多列（请参阅此stackoverflow问题，了解如何执行此操作：Can I add a column to slickgrid on on the fly?）
更新：示例仅显示前3列
插入此行：
columns = columns.slice(0, 3);
在以下行之前：
grid = new Slick.Grid("#myGrid", dataView, columns, options);
