HTML Tags

HTML is not supported for Appian UI building.

But, there is a grid component ....

Hi [mention:09cf3a8fdee34f5680a06848c77839c4:e9ed411860ed4f2ba0265705b8793d05] 

I have used <tr> and <td> in expression rule in this way for a PM to convert them into pdf 

a!localVariables(
concat(
a!forEach(
items: ri!list,
expression: {
concat("<tr><td>", fv!index, "</td>"),
concat("<td>", fv!item.Description, "</td>"),
concat("<td>", fv!item.Quantity, "</td>"),
concat("<td>", fv!item.Type, "</td>"),
concat("<td>", fv!item.Amount, "</td>"),
concat("<td>", fv!item.TaxRate, "</td>"),
concat("<td>", fv!item.TaxType, "</td>"),
concat("<td>", fv!item.TaxAmount, "</td>"),
concat(
"<td>",
fv!item.TotalAmount,
"</td></tr>"
),
}
)
)
)

/*once check it out*/

Not directly, but if your requirement is to remove the HTML tags and pull out the data from it for displaying it in any format as you like.

You can use this solution. It's very simple(Just striphtml function).  No need of regular expression or plugin hopefully..

YOU can use html tags when generating for example a Pdf from html, but not for displaying data in a grid.
