它是关于你在你的问题写了Excel的一个有趣的功能。我以前不知道这件事。
你需要的是实现一个custom formater函数。一般来说很容易。你应该编写一个小函数来显示基于值的单元格（颜色栏上的文本）。此外，你应该定义Unformatting custom function这将是非常容易的在你的情况。可以在排序和其他jqGrid操作期间使用unformating函数，其中需要从网格单元获取值。
所以你的问题可以减少到在颜色栏上显示数字。
已更新：我一次又一次地谈论你的问题，因为我发现使用颜色格式化数字可能会非常有帮助。所以我花了一些时间，创建了产生以下结果
，并可以现场here可以看到相应的代码示例。
对代码的小意见。我不得不创建其产生的任何现有的浏览器以外歌剧渐变栏是格栅被视为
的CSS类被定义为以下一些CSS类：
.cellDiv
{
left: 0px; top:5px; height:22px;
position:relative;padding:0;margin-right:-4px;border:0;
}
.cellTextRight
{
position:relative;
margin-right:4px;
text-align:right;
float:right;
}
.gradient1{
/* fallback (Opera) */

/* Mozilla: https://developer.mozilla.org/en/CSS/-moz-linear-gradient */
background: -moz-linear-gradient(left, #008AEF, white);

/*ie8*/
-ms-filter: "progid:DXImageTransform.Microsoft.Gradient(StartColorStr='#008AEF', EndColorStr='white', GradientType=1)";
position: absolute; left: -2px; top:-5px; right: 2px; height:22px; float:left;
}
.gradient2{

background: -moz-linear-gradient(left, #63C384 0%, white 100%);
background: -webkit-gradient(linear, left top, right top, from(#63C384), to(white));

position: absolute; left: -2px; top:-5px; right: 2px; height:22px; float:left;
}
和的jqGrid的$(document).ready(function() {/*code*/});内部代码：
var grid = $("#list");
var gradientNumberFormat = function (cellvalue, gradientClass, minDataValue,
maxDataValue, minDisplayValue, maxDisplayValue) {
var dataAsNumber = parseFloat(cellvalue); /* parseInt(cellvalue, 10);*/
if (dataAsNumber > maxDataValue) {
dataAsNumber = maxDataValue;
}
if (dataAsNumber < minDataValue) {
dataAsNumber = minDataValue;
}
var prozentVal = minDisplayValue+(dataAsNumber-minDataValue)*(maxDisplayValue-
minDisplayValue)/(maxDataValue-minDataValue);
return '<div class="cellDiv"><div class="'+gradientClass+'" style="width:'+
prozentVal+'%;"></div><div class="cellTextRight">'+cellvalue +
'</div></div>';
};

谢谢，这很有帮助。我仍然不确定格式化函数的作用是什么来生成数据栏。 – 2010-11-09 11:39:14
@M。 Cypher：可能我会稍后为你创建一个演示示例。 – Oleg 2010-11-09 19:19:53
@M。 Cypher：我对你很新。看看我更新的答案。 – Oleg 2010-11-13 16:24:44
