I wanted to add a tooltip to the columns in my table and I am using table.tagx by Spring Roo.
Because of the limitations in this tag you can't do it without changeing the tag library itself , I was able to do it and below are the steps to do that
- In the the table tag file where we are trying to add a new column to this table , under the td tag I defined the parameter title as title ="${colTxt}".
- But the colTxt is defined inside the td tag , so in order to allow the above to run we will have to define the colTxt filter before td like below
<c:set var="colTxt">
<spring:eval expression="item[column]" htmlEscape="false" />
</c:set>
Now the table will show tooltip/title for the columns in it.
Just in case if you need the whole tag file below is a copy paste of table.tagx file
