Maintain HTML from Sql server field in ASP.net form

I have a sql server table named ShopInfo that has a bunch of fields containing shop information

the shophours field contains the shop hour in an html table

the following is an example

<table width="100%" cellpadding="2" cellspacing="0" style="border:solid 0px #dcdcdc;"><tr><td colspan="2" style="background-color:#f5f5f5;border:solid 1px #dcdcdc;"><img src="./images/icon-clock.gif" style="vertical-align:bottom;" alt="" border="0" /> <b>Store Hours:</b></td></tr><tr><td style="border:solid 1px #dcdcdc; width:40%;">Monday-Friday:</td><td style="border:solid 1px #dcdcdc;">8:00am - 6:00pm</td></tr><tr><td style="border:solid 1px #dcdcdc;">Saturday:</td><td style="border:solid 1px #dcdcdc;">8:00am - 5:00pm</td></tr><tr><td style="border:solid 1px #dcdcdc;">Sunday:</td><td style="border:solid 1px #dcdcdc;">10:00am - 4:00pm</td></tr></table>

The html format for each of the shop hour entries is the same except for the hours themselves

I have attached a screen shot of what the generated html looks like

Currently, the user sends a request to IT if the hours need to change and we manually go into thetable and make the changes

The user would like a form to be able to change the hours themselves.

Trying to determine a way to present the info in a user friendly format to allow users to change hours and then write the updated html back to the table

Any suggestions as to a good way to approach this?
