Hello @Anonymous

For TextInput validation you can use IsMatch Function from this Link Here:
https://learn.microsoft.com/en-us/power-platform/power-fx/reference/function-ismatch

write the validation code on one errormassage label Like this

If(IsBlank(TextInput1.Text),"Enter Value in TextInput1",!IsMatch(TextInput1.Text, "[a-zA-Z0-9-]"),"Please Enter Proper Value in TextInput1")

and this code on visible property of errormassage label

If(IsBlank(TextInput1.Text) || !IsMatch(TextInput1.Text, "[a-zA-Z0-9 ]"),true,false)

To disable and enable the submit button write this code on Display Mode property of submit button

If(ErrorMsg.Visible,DisplayMode.Disable,DisplayMode.Edit)

Hi @Anonymous what @SanshubhLubal explained will work for you, at the point when you are creating the record (When you select NEW form)

But when you said across row, do you mean, you have a gallery that works like Excel??... is that what you have?

please elaborate, so that we can understand how to help you further.
