"And" is not working in datable.select

“OR” also is not working.

Yes, there is a matching row but I did some cleanup to get the matching data.
Below is the sample data

dtMasterTable:
Column5 123
Column9 1

dtTable2
column0 123
column4 '1

var1 = row(0).ToString().Trim()
var2 = row(4).ToString().Trim().Substring(1)

Removing ’ from row(4)
