使用位置数据文件时，突出显示特定列通常非常有用。在此类文件中，很常见的是有巨大的“区域”填充空格（或NULL值）并且只有非常稀疏的数据点。在这种情况下，读取文件会变得困难。

我发现简单地突出显示特定列很有帮助。起初，我尝试使用常规的 :match，但事实证明这方式会减慢大型数据文件的速度。我将此作为另一个问题发布。答案很简单。 cursorcolumn （自 vim 7.3 起可用）可以设置为一个范围，并且速度要快得多，因为它不需要匹配字符。

实施建议的解决方案后，我发现它有效。但这很麻烦，并且 - 了解 vim - 应该有一种更简单的方法来指定这一点。

问题：

是否可以将 cursorcolumn 范围设置为当前选定（可视）块的列？

When working with positional data files, it is often very useful to highlight a specific column. In such files it is quite common to have huge "areas" filled with spaces (or NULL values) and only very sparse data points. In such cases it becomes difficult to read the file.

Here's an example excerpt:

I found it helpful to simply highlight a specific column. At first I tried to use a regular :match, but this turned out to be way to slow on huge data files. I posted this as another question. The answer is simple. cursorcolumn (available since vim 7.3) can be set to a range and is a lot faster as it does not need to match the characters.

Implementing the proposed solution I saw it working. But it's cumbersome, and - knowing vim - there should be an easier way to specify this.

Question:

Is it possible to set the cursorcolumn range to the columns of the currently selected (visual) block?

事实证明这很简单。函数getpos可以检索任何标记的位置。我们将使用它来扩展之前问题的解决方案：

:let &l:cc = join(range(getpos("'<")[2], getpos("'>")[2]),',')

现在，我们可以轻松映射：

:vnoremap <F5> <ESC>:let &l:cc = join(range(getpos("'<")[2], getpos("'>")[2]),',')<CR>

因此，现在在编辑位置数据文件时，我们只需进入可视模式，选择我们需要的文件部分突出显示并按 F5

It turns out it's very simple. The function getpos can retrieve the position of any marker. We'll use this to extend the solution to the earlier problem:

:let &l:cc = join(range(getpos("'<")[2], getpos("'>")[2]),',')

Now, we can map this easily:

:vnoremap <F5> <ESC>:let &l:cc = join(range(getpos("'<")[2], getpos("'>")[2]),',')<CR>

So, now when editing a positional data file, we'll simply have to enter visual mode, select the portion of the file we need highlighted and press F5
