这是您在问题中写到的 Excel 的一个有趣功能。我以前不知道这件事。
您需要的是实现自定义格式化程序功能。总的来说是很容易的。您应该编写一个小函数,根据值(颜色条上的文本)显示单元格包含的内容。此外,您还应该定义Unformatting 自定义功能,这在您的情况下将非常容易。可以在排序和其他需要从网格单元格中获取值的 jqGrid 操作期间使用取消格式化功能。
因此,您的问题可以简化为在彩条上显示数字。
更新:我一次又一次地考虑你的问题,因为我发现使用颜色来格式化数字可能真的很有帮助。所以我花了一些时间并创建了相应的代码示例,它产生了以下结果

并且可以看到住在这里。
对代码的小注释。我必须创建一些 CSS 类,它们在除 Opera 之外的任何当前浏览器中生成渐变条,其中网格被视为

CSS 类定义如下:
.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) */
background: #008AEF;
/* Mozilla: https://developer.mozilla.org/en/CSS/-moz-linear-gradient */
background: -moz-linear-gradient(left, #008AEF, white);
/* Chrome, Safari: http://webkit.org/blog/175/introducing-css-gradients/ */
background: -webkit-gradient(linear, left top, right top, from(#008AEF), to(white));
/* MSIE http://msdn.microsoft.com/en-us/library/ms532997(VS.85).aspx */
filter: progid:DXImageTransform.Microsoft.Gradient(StartColorStr='#008AEF', EndColorStr='white', GradientType=1);
/*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: #63C384;
background: -moz-linear-gradient(left, #63C384 0%, white 100%);
background: -webkit-gradient(linear, left top, right top, from(#63C384), to(white));
filter: progid:DXImageTransform.Microsoft.Gradient(StartColorStr='#63C384', EndColorStr='white', GradientType=1);
-ms-filter: "progid:DXImageTransform.Microsoft.Gradient(StartColorStr='#63C384', EndColorStr='white', GradientType=1)";
position: absolute; left: -2px; top:-5px; right: 2px; height:22px; float:left;
}
和里面的jqGrid代码$(document).ready(function () {/*code*/});
:
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>';
};
