convert to proper case using dax

Question

I have a text column and would like to convert it to Proper. Is there a way to do it using DAX only? I dont want to use inbuilt powerbi functions

Proper case is any text that is written with each of the first letters of every word being capitalized. For example, "This Is An Example Of Proper Case." is an example of sentence in proper case. Tip. Proper case should not be confused with Title case, which is most of the words being capitalized.

for example

text_column
apple bat
cab

should change to

Text_column
Apple Bat
Cab

以下是如何使用 DAX 将文本字符串转换为正确的大小写。从示例表开始：

Table = 
    DATATABLE(
        "ID" , INTEGER ,
        "Text" , STRING ,
        {   
            { 1 , "The quick brown fox jumps over the lazy dog" } ,
            { 2 , "Happy Birthday" }
        }
    )

然后将此 DAX 代码添加为计算列：

Text Proper = 
VAR SplitByCharacter = " "
var var_text = 'Table'[Text] 
VAR Table0 =
    ADDCOLUMNS (
        GENERATE (         
            CALCULATETABLE( 'Table', 'Table'[Text] = var_text ), // we shrink table to current row only
            VAR TokenCount =
                PATHLENGTH ( SUBSTITUTE ( 'Table'[Text], SplitByCharacter, "|" ) )
            RETURN
                GENERATESERIES ( 1, TokenCount )
        ),
        //"Word", PATHITEM ( SUBSTITUTE ( 'Table'[Text], SplitByCharacter, "|" ), [Value] ),
        //"cnt", PATHLENGTH ( SUBSTITUTE ( 'Table'[Text], SplitByCharacter, "|" ) ),
        "Proper", 
            var word = PATHITEM ( SUBSTITUTE ( 'Table'[Text], SplitByCharacter, "|" ), [Value] )
            var word_Propper = UPPER( LEFT( word, 1 ) ) & LOWER( RIGHT( word, LEN( word) - 1 ) )
            return
                word_Propper
    )
RETURN 
    CONCATENATEX( Table0, [Proper], " " )

我受 Phil Seamark 文章的启发编写了这段代码：
