בטבלה הזאת יש שלוש עמודות, אבל העמודה האחרונה עדיין ריקה.

A common pronunciation is:

ba-tabla ha-zot yesh sha-losh a-mu-dot, a-val ha-a-mu-da ha-a-kha-ro-na a-da-yin rei-ka

More naturally, with a smoother flow:

Ba-tabla hazot yesh shalosh amudot, aval ha-amuda ha-acharona adayin reika.

A few notes:

• ח in האחרונה is the throaty kh sound, like in Bach.
• ר in modern Hebrew is usually pronounced in the back of the throat.
• Stress is often near the end:
  • taBLA
  • haZOT
  • amuDOT
  • acharoNA
  • reiKA

Because ב־ means in, and when it attaches to a definite noun with ה־ (the), they combine.

So:

• טבלה = table
• הטבלה = the table
• ב + הטבלה = בטבלה = in the table

This kind of contraction is very common in Hebrew:

• בבית = in the house
• בספר = in the book
• במכונית = in the car

So בטבלה הזאת literally means in this table.

In Hebrew, demonstratives like this and that usually come after the noun.

So:

• הטבלה הזאת = this table
• הספר הזה = this book
• הילדה הזאת = this girl

This is the normal Hebrew pattern:

• noun + this/that

Also notice that the noun is usually definite:

• הטבלה הזאת not normally
• טבלה הזאת

So Hebrew says something closer to the table this.

יש is the standard Hebrew way to say there is or there are.

So:

• יש שלוש עמודות = there are three columns

Hebrew does not use a structure like English there are with a form of to be here. Instead, it uses יש.

Examples:

• יש ספר על השולחן = There is a book on the table
• יש שני חדרים בבית = There are two rooms in the house

So in this sentence:

• בטבלה הזאת יש שלוש עמודות literally: In this table, there are three columns

Because עמודות is a feminine noun, and the number 3 must match that.

Here are the forms:

• שלושה is used with masculine nouns
• שלוש is used with feminine nouns

So:

• שלושה ספרים = three books (masculine noun)
• שלוש עמודות = three columns (feminine noun)

The singular noun is:

• עמודה = column

Since עמודה is feminine, its plural עמודות is also feminine, so the number is שלוש.

A strong clue is the ending ־ה in the singular form:

• עמודה = column

Many Hebrew nouns ending in ־ה are feminine.

You can also see the feminine agreement elsewhere in the sentence:

• שלוש (feminine form of three)
• האחרונה (feminine last)
• ריקה (feminine empty)

So the sentence is giving you several signals that עמודה is feminine.

Because in Hebrew, when a noun is definite, its adjective is usually definite too.

So:

• עמודה אחרונה = a last/final column
• העמודה האחרונה = the last column

This is a very important pattern:

• הספר הגדול = the big book
• הילד הקטן = the small boy
• העמודה האחרונה = the last column

So both the noun and the adjective take ה־ when the phrase is definite.

In present-tense Hebrew, the verb to be is usually omitted.

So:

• העמודה האחרונה עדיין ריקה literally: the last column still empty but naturally: the last column is still empty

This is normal Hebrew:

• הוא עייף = He is tired
• החדר גדול = The room is big
• העמודה האחרונה ריקה = The last column is empty

Hebrew does use forms of to be in past and future, but not usually in simple present-tense sentences like this one.

Because adjectives in Hebrew must agree with the noun in gender and number.

The noun here is:

• העמודה = the column
  and it is feminine singular

So the adjective must also be feminine singular:

• ריקה = empty (feminine singular)

Compare:

• עמוד ריק = an empty column / a blank column (masculine singular)
• עמודה ריקה = an empty column (feminine singular)
• עמודות ריקות = empty columns (feminine plural)

עדיין means still.

So:

• העמודה האחרונה עדיין ריקה = the last column is still empty

It shows that the situation continues up to now. The column was empty before, and it remains empty now.

Examples:

• אני עדיין מחכה = I’m still waiting
• הוא עדיין לא בא = He still hasn’t come
• החדר עדיין מלוכלך = The room is still dirty

The sentence has two parts joined by אבל (but):

1. בטבלה הזאת יש שלוש עמודות
   = In this table, there are three columns

2. אבל העמודה האחרונה עדיין ריקה
   = but the last column is still empty

So the structure is:

• location + יש + noun phrase
• אבל + subject + adverb + adjective

This is a very natural Hebrew sentence pattern:

• first, state what exists
• then, contrast it with additional information

Yes. In modern Hebrew, הזו and הזאת can both mean this for feminine singular nouns.

So both are possible:

• בטבלה הזאת
• בטבלה הזו

Very roughly:

• הזאת can sound a bit more formal or careful
• הזו is very common in everyday speech

A learner should understand both. In written Hebrew, הזאת is very standard.
