根据多数组中的键计算行跨度和列跨度数
我有这两种类型的布局,基本上,它可以是任何布局。我决定为此使用表格,因为使用 div 标签会导致某些可能的布局类型出现不良结果。
这里有两张图片描述了行和列的返回结果:

这将返回 $layout 数组,如下所示:
$layout[0][0]
$layout[0][1]
$layout[1][1]
在此布局类型中: $layout[1][0]
未设置,或未设置不存在。这里不存在第 1 行、第 0 列。那么我们如何使用它来帮助我们确定行跨度......?

好的,此布局类型现在将返回以下内容:
$layout[0][0]
$layout[0][1]
$layout[1][0]
$layout[2][0]
$layout[2][1]
$layout[3][1]
再次,有一些未在此处设置:
$layout[1][1]
$layout[3][0]
好的,我有一个名为 $layout 的数组,它在行和列上执行 foreach,但它不会抓取行和列未设置的列。因此,我创建了一个 for 循环(具有正确的行数和列数)。这是我到目前为止得到的:
// $not_set = array();
for($x = 0; $x < $cols; $x++)
{
$f = 0;
for($p = 0; $p < $rows; $p++)
{
// $f = count($layout[$p]);
if(!isset($layout[$p][$x]))
{
$f++;
// It could be a rowspan or a Colspan...
// We need to figure out which 1 it is!
/*
$not_set[] = array(
'row' => $p,
'column' => $x,
);
*/
}
// if ($rows - count($layout[$p]))
}
}
好的,$layout 数组有 2 个键。第一个键是 [row],第二个键是 [column]。 现在循环遍历它们并确定它是否未设置,告诉我需要将 rowspan 或 colspan 放入某处。我完全迷失在这里了。
基本上,我希望在这里返回一个数组,如下所示:
$spans['row'][ row # ][ column # ] = Number of rowspans for that <td> element.
$spans['column'][ row # ][ column # ] = Number of colspans for that <td> element.
它要么需要 colspan,要么需要 rowspan,对于同一个 元素,它肯定永远不需要这两者。另外,上面的图片仅显示 2 列,可以有超过 2 列。
任何帮助将不胜感激!
I have these 2 types of layouts, basically, it can be any layout really. I have decided to use tables for this, since using div tags cause undesirable results in some possible layout types.
Here are 2 pics that describe the returned results of row and column:

This would return the $layout array like so:
$layout[0][0]
$layout[0][1]
$layout[1][1]
In this layout type: $layout[1][0]
is NOT SET, or doesn't exist. Row 1, Column 0 doesn't exist in here. So how can we use this to help us determine the rowspans...?

Ok, this layout type would now return the following:
$layout[0][0]
$layout[0][1]
$layout[1][0]
$layout[2][0]
$layout[2][1]
$layout[3][1]
Again, there are some that are NOT SET in here:
$layout[1][1]
$layout[3][0]
Ok, I have an array called $layout that does a foreach on the row and column, but it doesn't grab the rows and columns that are NOT SET. So I created a for loop (with the correct counts of how many rows there are and how many columns there are). Here's what I got so far:
// $not_set = array();
for($x = 0; $x < $cols; $x++)
{
$f = 0;
for($p = 0; $p < $rows; $p++)
{
// $f = count($layout[$p]);
if(!isset($layout[$p][$x]))
{
$f++;
// It could be a rowspan or a Colspan...
// We need to figure out which 1 it is!
/*
$not_set[] = array(
'row' => $p,
'column' => $x,
);
*/
}
// if ($rows - count($layout[$p]))
}
}
Ok, the $layout array has 2 keys. The first 1 is [ row ] and the 2nd key is [ column ].
Now looping through them all and determining whether it's NOT SET, tells me that either a rowspan or a colspan needs to be put into something somewhere. I'm completely lost here.
Basically, I would like to have an array returned here, something like this:
$spans['row'][ row # ][ column # ] = Number of rowspans for that <td> element.
$spans['column'][ row # ][ column # ] = Number of colspans for that <td> element.
It's either going to need a colspan or a rowspan, it will definitely never need both for the same <td>
element. Also, the pics above show for only 2 columns, there can be more than 2 columns.
Any help at all would be greatly appreciated!

为什么不存储 colspan &原始数组中的 rowspan 数据,而不是尝试导出它们?像这样的东西:
Why not store the colspan & rowspan datum in the original array, rather than trying to derive them? Something like this:
