Partial fix to delete row functionality

[jorgerojas26]

This is a partial fix to be able to mark and unmark rows to be deleted and keep row coloring.

But i am aware there are a lot of problems to keep the state of the changes being made to the rows (update, delete, append).

I will make a huge revamp to that logic in another PR.

Fixes #153

Typo spotted: functionality, not funcionality

I would like to suggest

Suggested change

	func (table *ResultsTable) isAnInsertedRow(rowIndex int) (isAnInsertedRow bool, DBChangeIndex int) {
	for i, dmlChange := range *table.state.listOfDBChanges {
	values := dmlChange.Values
	for _, value := range values {
	if value.TableRowIndex == rowIndex {
	cellReference := table.GetCell(rowIndex, 0).GetReference()
	isAnInsertedRow := cellReference != nil && cellReference.(string) != "NULL&" && cellReference.(string) != "EMPTY&" && cellReference.(string) != "DEFAULT&"
	if isAnInsertedRow {
	return true, i
	}
	}
	}
	}
	return false, -1
	func (table *ResultsTable) isAnInsertedRow(rowIndex int) (isAnInsertedRow bool, DBChangeIndex int) {
	for i, dmlChange := range *table.state.listOfDBChanges {
	for _, value := range dmlChange.Values {
	if value.TableRowIndex != rowIndex {
	continue
	}
	cellReference := table.GetCell(rowIndex, 0).GetReference()
	if cellReference == nil {
	continue
	}
	switch cellReference.(string) {
	case "NULL&", "EMPTY&", "DEFAULT&":
	continue
	default:
	return true, i
	}
	}
	}
	return false, -1

this is pseudo code written on my phone, please check it

But maybe this would be more efficient

	func (table *ResultsTable) isAnInsertedRow(rowIndex int) (isAnInsertedRow bool, DBChangeIndex int) {
	for i, dmlChange := range *table.state.listOfDBChanges {

	if value.TableRowIndex == rowIndex {
	cellReference := table.GetCell(rowIndex, 0).GetReference()
	isAnInsertedRow := cellReference != nil && cellReference.(string) != "NULL&" && cellReference.(string) != "EMPTY&" && cellReference.(string) != "DEFAULT&"

	return true, i
	}
	}
