如何在jqGrid 4.0中合并单元格 [英] How to merge cells in jqGrid 4.0

问题描述

我一直试图在jqGrid中合并"单元格，也就是说，我想使特定行的单元格具有colspan = 2(或更多).到目前为止，我已经可以使用列模型中的 cellattr 选项使边框正常工作，如下所示:

I've been trying to "merge" cells in a jqGrid, that is, I want to make cells for specific rows have a colspan=2 (or more). So far I've been able to get the borders to work properly using the cellattr option in the column model with something like this:

colModel = { name: "a", width=50, 
             cellattr: function(rowId, tv, rawObject, cm, rdata) {
                          if (rowId < 5) { return 'sytle="border-right:0px"'; } },

             name: "b", width=50, 
             cellattr: function(rowId, tv, rawObject, cm, rdata) {
                          if (rowId < 5) { return 'sytle="border-left:0px"'; } } };

这只是删除了我要合并的单元格的边框(第5行的a& b).但是，如果我将文本添加到任何这些框中，则text-align显然将无法正常工作，并且如果文本大于50像素，则会被截断.

This just removes the border for the cells that I want to merge (a & b up to line 5). But if I add text to any of these boxes text-align will obviously not work properly and the text just gets cut off if it is larger than 50 pixels.

我可以做一些疯狂的事情，将所有文本切成两半，然后分别将每个半部分分别添加到右对齐和左对齐下的"a"和"b"列中，以进行居中对齐.但是，似乎应该有更好的方法.

I could do some crazy thing where I do center-align by cutting all the text in half and add each half to column "a" and "b" under right-align and left-align respectively. However, there seems like there should be a better way.

推荐答案

我发现您的问题非常有趣，因此我+1.

I find your question very interesting, so +1 from me.

在我看来，colspan=2的用法才是您真正需要的.要使具有colspan=2的行中的列数相同，我建议隐藏该行中的下一个<td>元素:

It seems to me that the usage of colspan=2 is what you really need. To have the same number of the columns in the rows having colspan=2 I suggest to hide the next <td> element in the row:

{
    name:'a',index:'a', width:50,
    cellattr: function(rowId, tv, rawObject, cm, rdata) {
        if (Number(rowId) < 5) { return ' colspan=2' }
    }
},
{
    name:'b',index:'b', width:50,
    cellattr: function(rowId, tv, rawObject, cm, rdata) {
        if (Number(rowId) < 5) { return ' style="display:none;"' }
    }
}

我只测试了几次实现，但似乎可行:

I tested the implementation only a few time, but it seems to work:
