Lua:向表中添加多行 [英] Lua: Adding multiple rows to tables

问题描述

好，所以我希望快速生成一个很大的表.看起来像这样:

Ok, so I'm looking to quickly generate a rather large table. Something that would look like this:

table{
{1, 1, 1, 1},
{1, 1, 1, 1},
{1, 1, 1, 1},
}

只有表将包含更多的行，并且这些行中的值也更多.我知道使用table.insert()可以轻松地在一行中添加任何我需要的内容，但是无论如何我也可以在不键入全部内容的情况下添加整个新行?

Only the table would contain far more rows, and far more values in those rows. I know using table.insert() I can easily add however many I need to a single row, but is there anyway I can also add whole new rows without typing it all out?

推荐答案

使用for循环.

t = { }
for i = 1,100 do
    table.insert(t, i) -- insert numbers from 1 to 100 into t
end

二维数组也非常简单

t = { }
for row = 1,20 do
    table.insert(t, { }) -- insert new row
    for column = 1,20 do
        table.insert(t[row], "your value here")
    end
end

您可能还记得local current_row = t[row]中的当前行，但是在进行概要分析之前，请勿尝试使用这些方法来提高性能！如果您认为更清楚地表达了目的，则仅将它们用于可读性.

You could remember current row as in local current_row = t[row], but don't try these things to improve performance until you profile! Use them merely for readability, if you think it clearer expresses the purpose.

还要注意(在5.1及更高版本中，#尤其时髦)，您可以直接将值分配给不存在的索引，然后将它们添加.

Also note that (and it's especially funky in 5.1 and newer with the #) you can just directly assing values to nonexisting indices, and they will be added.
