I need at the end of the table the last TR to be the total width of the table ( col-xs-8 col-sm-8 col-md-8 col-lg-8
) and that has a text field, I tried several ways but I can not do that.
Edit1: The table in code is in the following structure: Iwouldliketoinsertanewrowattheendofthetable,thislineshouldhavethemaximumwidthofthetablelikethis: And finally on this last line put a text field with the same width of this line.
