Date in column header won't work in formula

[canefan17]

I've built an amortization table and have dates as column headers.
1/1/2019, 2/1/2019, 3/1/2019,...

In another table I have Start Date and End Date columns. I've built a formula that essentially says, =IF(AND(1/1/2019 is > Start Date, 1/1/2019 < End Date),"TRUE", "")

So if it's between the start and end date I want a "TRUE" result.

This formula works fine when I have my data in just a range. (as you'll see in the file).
The second I turned that range into a table the formula gave me a false reading (because the dates in the column headers are now acting as TEXT and not DATES, despite me changing the format to date).

How can I fix this or workaround it?

See file attachment.

Will you please attach a small sample Excel workbook? We are not able to work with or manipulate a picture of one and nobody wants to have to recreate your data from scratch.

Instructions (Please Read Carefully):

1. Make sure that your sample data are REPRESENTATIVE of your real data. The use of unrepresentative data is very frustrating and can lead to long delays in reaching a solution.

2. Make sure that your desired results are also shown (mock up the results manually).

3. Make sure that all confidential data is removed or replaced with dummy data first (e.g. names, addresses, E-mails, etc.).

4. Try to avoid using merged cells as they cause lots of problems.

Unfortunately the attachment icon doesn't work at the moment (it hasn't worked for years, and despite our repeatedly asking the technical team who own the forum to fix it, they can't be bothered to do so), so to attach an Excel file you have to do the following: just before posting, scroll down to Go Advanced and then scroll down to Manage Attachments. Now follow the instructions at the top of that screen.

Please pay particular attention to point 2 (above): without an idea of your intended outcomes, it is often very difficult to offer appropriate advice.

I have attached my file.

You will see the 2 amortization tables on the right.

1 is just a range of data (and gives me the correct results), and 1 is a table (which gives me blanks despite it being the same formula.

I suspect the table isn't working because the headers are dates, and Excel apparently auto-formats them to text (which means the IF formula isn't effective anymore).

How can I get those date headers back into date format? I've tried many things to no avail.

Edit:
H$28*1 also works

Thanks. I ultimately decided to just put a row above the table with the dates, and then hide the row.
