Question

我正在尝试将表格的输出减少到以下列

$tcolumns = "JobName,VMname,Sunday 08-06-2014,Saturday 07-06-2014"

$Report = $table | select $tcolumns | ConvertTo-HTML -head $style

输出一个包含空列

的表

如果我

$report = $table | select JobName,VMname,"Sunday 08-06-2014","Saturday 07-06-2014" |    ConvertTo-HTML -head $style

输出正常。

关于如何使用变量来定义我想要返回的表列的任何想法？

$ table |的OUTPUT得到构件

Answer 1

如此处所述（PowerShell Display Table In HTML Email）使用ExcludeProperty

$DataSet.Tables[0] | select * -ExcludeProperty RowError, RowState, 
    HasErrors, Name, Table, ItemArray | ConvertTo-Html

Answer 2

你想要一个字符串数组，而不是一个恰好有逗号的字符串。： - ）

$tcolumns = "JobName","VMname","Sunday 08-06-2014","Saturday 07-06-2014"
